XnView Software

Sent. The bug is still present in 0.71 I've just tried.

one more thing - if i choose startup folder as "none", XN starts fine

If it's any help, here are the two ini files - one which works ok, other which crashes xnview. Problem is clearly in "geom" setting

same issue here with current version of XnView. If I resize the window above certain size (does not have to be maximized), close it and reopen again, it crashes...
Guess there could be some issue with HiDPI displays? I use it on 3200*1800 screen with 150% dpi size, Win8.1 with latest updates.
