Re: Possible bug...

[Richard van Zon <rvanzon@xxxxxxxxxxxx>]

well...hm...I found it...but I am not very happy ;-)
it is something with my OpenAL-code (realocation of the sound sources 
seems to be
the problem) in a function that is called before the keydown();...
but I dont see why S-Lang gets involved with that...it has actually 
nothing to do
with the keydown or anything with the engine...
but I have to work around that then...

thanks for the help..again..
