Keyboard and Mouse controls disappeared

[Meow]

As well as some settings, like the OSD font preferences.
I don't really know why or how.
This seems to occur after some buggy movie or codec's been played and made bsplayer crash which required me to close it.
I can't seem to get the keyboard shortcuts or mouse-wheel to control the bsplayer screen anymore. The size-control by scroll-wheel, as well as the F key for full screen, the 1, 2, 3 keys for size, and the up-down arrow for volume etc. seem disabled.

Where is this stored/set ?

This applies to the following:
BSplayer 1.37 build 826
Windows 2000 updated to today's latest MS patches.
Video: GeForce 6200, NVIDIA compatible, 1280 x 1024 at 32 bit with 60 Hz.

I've had this before, and after I ran the installer (a new version had appeared) it was gone. This time that trick doesn't work. Probably because there's no new version? It might be solved when I uninstall and reinstall, but then again, this is something I thought you should know about.

Thanks for any advice.
