XnView MP freezes when the catalog is auto-updated

[woot000]

These bugs have been occuring on Windows 11 22H2, using XnView MP 1.3.1 x64, with the catalog enabled (bugs likely also occur when the catalog is off, given enough time is spent for XnView MP to generate a catalog)

Whenever the catalog is updated in any way (moving, creating, renaming, copying or deleting a file, either within XnView MP or through File Explorer/some other external program), the viewer freezes while the catalog is updating to reflect the change. XnView MP is unable to be used at all while it is frozen, and animated images/videos will stop when the program is frozen.

The time that XnView MP is frozen depends on how many images are open, and how many files are located in the folders that the images are open in.

In a folder with 5500 files, the freeze is barely noticeable when just 11 images are open (about half a second for me), but is significantly prolonged when about 40 images are open (about 2 seconds).

lots_of_images.mp4

These are the two bugs that I've experienced: the catalog updating freezes XnView MP when it shouldn't, and (I'm fairly certain) the catalog updating multiple times per number of images open when it should update just once.
