losing images in browser

[tomcom]

i'm having a big problem losing images every time i re-open the browser.
jpegs that i have in folders suddenly become unviewable.
"no preview available" & the thumbnail appears as just a jpeg icon.
it's happening in every folder & i'm losing 20 or 30 images or more each day. properties do show the size but trying to open with any image viewer
returns error messages. Paint Shop Pro gives me a "not valid jpeg" message.
had this bug once before after an update & now it's back again after the most recent update.
the main point here is that i have the image one day & the next time i open the same folder it's gone.
i'm also getting a lot of flickering as the browser scans & loads the thumbnails.
any help will be greatly appreciated.
thanks
tom

Hello !

• I never noticed such an issue, maybe might you check these image-folders for viruses, that sounds a bit like this…
- XnView indeed doesn't change¦delete files without requests and confirmations !

Kind regards,

no,definately not a virus.
i did have this problem before w/ XnView & pierre did respond with
checking some setting in the program.
i could open the browser now in a folder and see the thumbnails & images ok.then if i exit & then re-open to that same folder a number of images will be unviewable when i just viewed them moments ago. the only constant is XnView.
