I can confirm that the problem is fully reproducible when browsing files in format that loads slower than JPGs (like HEIF).
When you try to open the image from the list, and this image is not loaded to the preview yet, the one in the preview will be opened, not the one double clicked.

1.9.2 [Windows] Thumbnails in Full Screen are in incorrect size
Hello,
Looks like when you open an image from Windows Explorer by double clicking on it, and the image opens in Full Screen mode, the thumbnails are always in "default" size, not the size set in the settings.
Opening a Full Screen mode from the Browsing Mode respects size of thumbnails set in ...

Re: 1.9.2: Read Ahead does not seem to be working for HEIC
Ok, seems like I have this problem on one system.
But it's not files related, as when I copied the entire folder of 120 files to another computer, the problem was not there.
Is it possible that the size of Thumbs.db makes this difference?
On the "slow" system Thumbs.db has 250GB.

Re: 1.9.2: Read Ahead does not seem to be working for HEIC
Hi,
I can't reproduce it either now
Looks like the slowness was caused by the thumbnails being regenerated in the background.
As they are ready now, I confirm, that the "next" image is shown immediately.
I'm sorry for false alarm

Re: Force thumbnail building on directories with thousands of files
I'm having the same problem with thumbnail generation.
Looks like the only way to import the folder with hundreds of subfolders is to click "Show all files".
But it doesn't work for hundreds of thousands of images, as XnView uses ALL memory and crashes.
:O
Do you have any idea how to generate ...

Full Screen: Ability to select multiple images to delete them
Hello,
When in Full Screen mode, it would be really helpful to have the ability to select multiple images on the thumbnails view that is visible when mouse reaches the top of the screen.
When reviewing series of images, the best way to review them is in Full Screen mode.

Full Screen: Click to Zoom to 1:1, Click and hold to Pan in 1:1 Zoom
Hello,
When in Full Screen mode, it would be really helpful to have the ability to Click the mouse button to zoom to 1:1 and that zoom would stay there.
Clicking again would revert the Zoom to previous value.
Right now it is a little problematic, when viewing through hundreds of images to review ...

1.9.2: Read Ahead does not seem to be working for HEIC
Hello,
I have Read Ahead next image enabled and am mainly viewing .HEIC images which are quite large, over 8000 pixels wide, 15-18MB in size.
I assume that Read Ahead should immediately display the next image if it is cached.
However, it doesn't seem to work that way.
I open the first image, wait ...
