I am testing XnView v1.93.2 in a Windows XP SP2 installation.
The problem just happens with this latest version. All other versions are working fine including v1.93.1.
I always use XnView with a "Null Startup Path" to open the program in one non existing folder. This never generates any error with the toolbar before (I used it totally hidden).
Here the bug/hidden toolbar doesn't appear (v1.93.1).
Now the bug/hidden toolbar appears on the halfway (v1.93.2).
If I click in any folder at the tree, then the bug/hidden toolbar disappears for the currently session. But when I open XnView again, there it is…
If I set XnView to open in any predetermined folder, then I can see briefly the toolbar hiding itself.
Thanks very much for this great program.
