winamp crash on minimize with matrox / nvidia combination

[Conz]

winamp crashes withouth a message when it is minimized while i'm running 'matrox multidesk' wich is matrox' virtual desktop program.
this system is an athlon 1.33Ghz with a gf3 ti200 detonater 21.88 and a matrox pci g450 with 5.82.14.0 (beta) drivers.
this is running on win2k sp2 NL.
the problem doesnt occur when multidesk isnt running, then winamp works fine.
