The thumbnails always refresh when I open the program; if I have a lot of folders and other files within a directory, and I open one of those folders, then go back out to the directory, all the thumbnails refresh again, even though I haven't changed anything. It takes a long time to refresh them all when I have a couple hundred or more items in the directory. It's annoying that if I wait for all the thumbnails to refresh, then go into one of the folders and back out, they all have to refresh again.
I've looked at all the settings but I can't find where to disable this auto refreshing, if there is a way.
If anyone knows the answer, I'd be eternally grateful!

Re: How to stop thumbnails from constantly refreshing
There's no "disable auto refreshing" setting. But XnViewMP can do thumbnail caching, which saves and re-uses previously generated thumbnails.
It sounds like you have thumbnail caching turned off. Check your settings in Setting:Catalog.
You need to ensure Enable Thumbnail Caching is checked, that that "maximum size for cached thumbnails" is adequate if you have that setting also enabled.
If it's jpeg images you're concerned about, those have embedded thumbnails. You can make thumbnail display really fast by using that embedded thumbnail instead of generating one. To do this, go to Settings:Thumbnail and enable "Use Embedded Thumbnail".
There is another option that goes with that one: "Create from original image if embedded thumbnail is smaller than thumbnail size". This refers to the thumbnail size you have set in the browser, either with the thumbnail scaling toolbar slider, or View->Thumbnail size, or Settings:Thumbnail:Appearance.
The normal size for an embedded jpeg thumbnail is 160x120, but some camera manufacturers (Nikon for example) embed multiple thumbnails in larger sizes. If your browser thumbnail display size is larger than the embedded thumbnail size, this setting controls whether the whole image will be resampled to create the new thumbnail (slow) or just upsize the smaller embedded thumbnail (fast but lower quality).
If you use the embedded thumbnail, and disable "Create from original image if embedded thumbnail is smaller than thumbnail size" then thumbnail display will be very fast even if you have thumbnail caching turned off.
If your thumbnails are getting slowly regenerated every time you re-enter the same directory, it sounds like you have your settings set exactly wrong: with caching disabled, and a larger size thumbnail display with "Create from original image if embedded thumbnail is smaller than thumbnail size" enabled. That's the combination of settings that will produce the worst possible performance.
So check your settings and report back if that resolves your problem.

Re: How to stop thumbnails from constantly refreshing
I changed my settings to the ones you specified and waited for the program to refresh all the thumbnails. Sadly, it didn't fix the problem, when I opened a folder inside the directory then went back out, all the thumbnails were blank again. But they are refreshing faster, so that's a plus.
Re: How to stop thumbnails from constantly refreshing
Somethings's not right. Suggest you delete your settings and start with a fresh copy of the app, or post screenshots of your settings.
What file types are we talking about? Jpeg or something else?
If you have hundreds or thousands of images in a single folder, it will take a few seconds to load them all, even from cache when they don’t actually regenerate; but the first ones will display instantly.
