There's a long list of bugs in the NS package - it would be great if  
people who know a bit of C or ObjC could take a look.

I suspect that this one is easy to fix - just make sure the cursor is  
re-drawn when changing text with mouseover property (mouse highlight).

Yeah, I notice that turning on blink-cursor-mode makes this problem go  
away.
