Cursor-tracking glitches, where the cursor doesn't revert when exiting 
a view, are really common in Cocoa apps. I see them in all kinds of 
apps, even major Apple ones like Mail and Xcode. I think it's due to 
bugs in AppKit, unfortunately. These bugs have been around since at 
least 10.0, but they've never been fully tracked down and fixed.
