This sounds very familiar to a problem I had a while ago, and maybe it's
what you're seeing. Basically, invalidateCursorRectsForView: stops
working if resetCursorRects: adds no cursors. In my app, depending on
modifier keys and other stuff, sometimes in my resetCursorRects: method
there are no cursors I want to add. But if you don't add at least one,
invalidateCursorRectsForView: won't work anymore. My workaround was to
always add at least one, like this:
[self addCursorRect:NSMakeRect(0,0,1,1) cursor:[NSCursor arrowCursor]];
This bug is about 4 years old, but not fixed:

If this if your problem too, please file another bug, maybe it'll get
fixed this decade! :)
