thumnbnailhandler don't work on all icons

[happyscraparts]

Hi
I just had a reinstallation of my system (windows 7 ultimate) and I reinstallend the thumbnail handler to be able to see the image on my psp files.
(I use paint shop XII) I does work on some icons, but not on all.

I also made sure the first item "always show icons, never show thumbnails" does NOT have a check in the file and search settings.
Strange also is that sometimes an icon does show the imgae and when I get back to that file later is doesn't show it anymore and I just see the icon.
Also when I click on save and the window opens I can see all the images with a psp extension, so there it does work.

I had windows 7 home (x64) before reinstalling and the thumbnail handler worked great for me with that.
I did restart the computer. I did try to deinstal en reinstall too. That doesn't change it.

Can anyone help me out here.

thank you

Try this. Open file explorer, View, Options then click the View tab. At the very top under Advanced settings there is a tick box Always show icons, never thumbnails. If this is ticked, un-tick it then click ok. If it isn't ticked, tick, click ok. Go back to the same again and u-tick then ok. See if that works for you. I can see ALL my PspImages after doing this. Thanks to the tip off PSP developers.
