On Windows XP, Wish sometimes crashes after showing a dialog box stating "Tried to free a color that isn't allocated.".
For me, this happens whilst running a Tk application when another application (e.g., a game) takes over the full screen and changes screen resolution (and probably screen color mode).
Other users have seen this as well seemingly from time to time. Refer, e.g., to http://www.amsn-project.net/forums/viewtopic.php?t=584.
This might well be a reoccurrence of bug #570748 (http://sourceforge.net/tracker/index.php?func=detail&aid=570748&group_id=12997&atid=112997).

Confirm for 8.4.15 and today's 8.5beta.
If we call XAllocColor in non-palette mode, than switch to palette mode and call XFreeColors, the latter will free resources, which were never allocated. :-)
Again, we get a memory leak in opposite case.

Probably, not an elegant patch, but works for me.
