Does that tell us anything?
In a way!
There might be some app that runs either by timer like an AV scan, or one that burbles along in the background like my latest (and I hate it, and turned off the auto feature) version of Executive Defragger.
When the auto feature, which is described as defragging my hard drive constantly as I worked, but deferring the computer resources to whatever application I was running when it needed them.
So, it messed up two programs on my machine..... Acronis, and AVG, and two different ones on my wife's computer.
The problem only appeared during some conflict between the Defragger and AVG or Acronis. Otherwise, one wouldn't know there was a problem with it.
That's the type of thing I would be looking at/for.
That's why a week or so ago, I mentioned perhaps, trying a system restore back to when there was no Problem with Qimage, and see what software had not yet been added.
