OS: Windows 10 64-bit
This is a long-lived bug; I've noticed it for years but haven't gotten around to reporting it. When opening XnViewMP and resuming a previous session, with more than one or two tabs open, it will crash after several seconds, with no crash reporter.
This seems to happen intermittently, but usually requires 3+ tabs, all viewing images in folders containing many other images. It crashes after working fine for a few seconds, while the browser is loading thumbnails (though I don't know if that's part of the issue).
Closing all but one or two tabs before it crashes usually keeps it from crashing.
Effect: it crashes.
To reproduce:
1. Open 5-6 tabs viewing images in separate folders of hundreds to 1000+ images
2. Close XnViewMP
3. Open XnViewMP
Actual behaviour (bug): crashes on startup

Expected behaviour: resumes previous session correctly, without crashing.
