Winamp freeze Window 7 box solid

[bullshark]

Hi, great fan of Winamp.

I recently move to Window 7 x64 rc1 due to memory requirement of some software I run.

Unfortunately, that spell disaster for Winamp who now not only freezes, but freeze the whole box solid. No BSOD, just completely frozen computer.

It seem to happen mostly when I try to manage file, like if I create a new playlist and try to drag audio file to it, boom, instant freeze, or if I even hover over the "send to". Happen whether there's audio going on or not. Doesn't freeze when just playing back of single file.

Window media player work fine, so is Foobar and media center on this box.

Winamp 5.56 full, clean install, no extra plugin whatsoever.

Tried running Winamp in compatibility mode, no difference, turned UAC on-off, no difference.

Window 7 x64 rc1 build 7100.
