Hi Jules,
Since no one else has reported such an occurrence in a long time, if ever,  it is likely some combination of events such as an antivirus or similar anti spyware interference.
Regardless, the bottom line is: It's time to move to a fully supported Qimage Ultimate.
You will love it!

Fred

Jules,
In a previous post, I advised that you upgrade to Ultimate. I still advise the same, but I need to mitigate that by saying that I spent about a half hour or so really investigating the reports of Invalid Pointer Operation.
It appears that Ronzie hit the nail on the head.  About 75% pf the replies refer to some other program either using memory and not releasing it, or the Operating system in disagreement with some program on memory allocation.
The other 25% seem to favor some Malware.

Since we have thousands running Studio with no similar error messages, it has to be some program on your machine in conflict with memory allocation somewhere.
There were a few tech replies that said the fix was to go to Windows 7 which had far superior memory management.

With regard to upgrading to Ultimate, all your saved setups and jobs will be migrated to a new folder and you still keep and use them.

I know it's a pain to suffer these error messages, and many pieces of advice do not always effect the cure, so I am suggesting that you might think of checking your memory for no bad sticks, and then moving up into W7 to see if that cures the error message.
I also suggest W7 because program authors writing software try to use the tools that W7 offers, and sometimes, XP users suffer.
So that's how you could possibly have a conflict over memory chunks.

I wanted to you to upgrade to Ultimate mainly for you to get the full benefit of the latest upgrade to printing quality (Fusion, found only in Ultimate) plus all the other goodies like Tone Targeted Sharpening, etc.

Ultimate might cure the Invalid Point error message, but you will have to at least try the DEMO version to see.

Thanks for listening.
Fred

Fred. I downloaded Q Ultimate and opened it, it asked to delete the existing thumbnail cache and I ok'd that. It opened fine and after a bit loaded my thumbnails. I Recalled a print job which it loaded fine. I have now reopened ultimate about five times and tried different things/images/jobs. Everything seems to work fine EXCEPT clicking on the Edit Page (lower right under image) OR CTRL/E or R/Click image and choose Edit Image from there. All of these open the Edit page for a fraction of a second and then the programme crashes out. This happens in Ultimate, just as it did in Studio. It is obviously something to do with opening the Edit page. Have you any idea what it could be and why it is happening. Any advice as what to do? There is no point me buying Ultimate if this happens with it as well as Studio is there. I guess it is my computer as no one else has complained about this, but what can it be?
Desperate

I am going to try a SAFE MODE boot and see if Qimage runs like that.
You might try that too.

That is a bit beyond my skills Fred. I know what is is but am not confident enough to try it without someone holding my hand. Why would it change the way Q would run?

Hi mike. I have now tried different images and a jpg from a different source and am now managing not to get any crashes. I did run C Cleaner and maybe this has helped. PhotoShop which I also use on this PC is always stable. It seems to be intermittent which of course makes things more difficult to pin down. I have had this problem in the past with Studio and then it has gone away and then returned so I will monitor things and report back. It is in fact the only problem i have had with Qimage generally. But hopefuly, things this morning do seem to be better. I have tried different files and formats in both Studio and the trial version of Ultimate. At one point I did get this error... Access violation at address 00423048 in module 'Qimage'exe' . Write address 9D85B529  Does this mean anything to anyone? I have tried a file straight from camer and this too seems to able to be Edited too without problem.
Thanks for your help. I just hope thisngs stay stable now.

Next crash go to the XP Control Panel, Administrative Tools, and click Event Viewer. Look for any read error events. Double-Click on the event and see what info it offers, if any. Click the down arrow box to read the next until you are past the sequential read tagged errors.

Maybe something meaningful will give you a clue.

The events are last at the top and you scroll down for earlier time stamped events.

There is a free system utility that can help from MS. Go to:
http://technet.microsoft.com/en-us/sysinternals/bb545027
Download Process Explorer v14.12 (May 18, 2011). Unzip the .exe into a convenient folder and create a shortcut to it. Start it up.

Right click on its status bar at the left bottom of its window. Set it up like the attached image. keep an eye on physical ram by alt-tabbing to it. If you happen to have a dual monitor setup for editing place that window there. If it looks like physical ram keeps climbing near a hundred percent. Also right click on the column header bar. Add virtual size as in the other attached file. See what process is eating up the virtual ram.
