Hi,
However that info no longer appears at the bottom of the screen when the mouse hovers over a thumbnail
I have an NAS drive which hardly use now (it's old & slow) but it still has some images on it, both raw and jpegs.
I just fired it up to see what happens.
I have the Photos Directory on the NAS mapped to a drive letter and if I access the photos via that drive letter, eg. P:\1-CANON350D_V12_04-05\2012-04-14 Braunston,
all works as expected. Instaview and the Hotbar show the image data.
If I access the photos via the Network, eg. \\Mybookworld\pictures p\1-CANON350D_V12_04-05\2012-04-14 Braunston then I get the same problem as you, no data in the Hotbar.
I haven't a clue why this happens, some weird network thing no doubt. I suggest that you map you photos directory on the NAS to a drive letter and work through that.
