Crash when trying to "play" menudef.dat

[LoKi128]

When I associated all the files that BSP can play, it also associates .DAT files... so out of curiosity I tried to open menudef.dat in the player. It crashes with the following messages:

BSPlayer v0.85.488, Unhandled exception at EIP: 004BC643
Application will be terminated.

Of course, I don't expect BSP to load a non-media file (heh) but it shouldnt crash either.

BTW just started using the player today... GREAT WORK! THANK YOU!
