Using ShowWindow causes Winamp crash at exit

[SinePi]

My plugin uses its own window (RegisterClass, ShowWindow, etc.) to display some data. When I close WinAmp, there's a GPF somewhere in its code (not in mine). If I as much as remove the ShowWindow line, there's no error at all. Is there something that I should pay extra attention to take care of?

Hell yeah! Like our search engine?

are you subclassing winamp? if so are you gracefully handling that? are you making sure you destroy the window you've created when you get your quit(..) called? are all threads/anything else which could leave itself as a reference point in winamp been closed and correctly cleaned up?

Most crashes when exit winamp is because something on your plugin is crashing on quit.
Did you test what happends if you only deselect your plugin in the preferences window of winamp? Crashes the same?

... I don't know what I did, but the crashes stopped. However, they were happening after my quit() code, and by looking at the disassembled code - when WinAmp was trying to call quit() on another plugin (the same code point, a call, that sent the instruction pointer into my quit(), crashed on another turn of what seemed to be the shutdown-all-plugins loop).
Thanks for the swift response, however.
