I'm having a similar problem ? slightly different symptoms. My usual usage pattern is to open the first picture in a directory with IrfanView's main viewer and navigate from there. When I first select the thumbnail view, it takes a very long time to display. For one small directory (34 JPG files/2.4 MB total) it took 95 seconds to finish the display; for another (11 JPG files/3.9 MB) it took 70 seconds. The thumbnail window opens instantly, the names of the files appear shortly afterward, then there is no visible change for a long time, finally the thumbnails appear (very quickly).
The vast majority of the time (say 93 of the 95 seconds) was during the "no visible activity" period. There doesn't seem to be a lot of CPU activity during this period. Memory doesn't seem to be an issue ? right now Windows Task Manager shows 0.75GB of 1.5GB available. It doesn't seem to be tied to background activity ? it's worse, of course, when I have something else running but still bad when I don't. I just ran a test after a fresh boot: 4 JPG files, 1.4MB, 58 seconds!
A refresh of the thumbnail window runs fairly fast. If I close the thumbnail window and reopen it, the thumbnails usually appear very quickly. If I close IrfanView completely and repeat, the thumbnails usually appear slower, but still much faster than the first time. If I don't use IrfanView for a while, the problem reoccurs.
I've been using IrfanView for a long time (starting with version 2.x) and didn't used to have this problem. I don't remember when this problem first surfaced, probably around version 3.7. Today I installed version 4.10 and ran the test cited above. The thumbnail size is 80x80, all other options are off.
Any ideas?
