cant enter preferences panel

[blurpnroll]

i'm experiencing the following problem on two boxes running w2k pro and w2k server:

I can just enter the preferences panel (either from contex menu or by hitting ctrl+p) if bsplayer is not currently played playing a file, otherwise i get this message.

bsplayer doesnt crash, anyway, it keeps playing the movie and since then trying to enter preferences does nothing at all.

I've got DivX 5.0.3 installed and the problem also occurs playing mpg and asp files.

Any ideas about the causes of that?
TIA
