However there is also a single issue that causes Rebol/View 1.3.2 to crash and I've backtracked it to be a part of some FEEL code that uses DETECT to detect when the icon should be highlighted according to mouse position. Along with this, you need to have an INFORM window open. REBOL/View crashes when you close the INFORM window. All of this has been reduced a while ago into RAMBO entry #4137.

It's rare, but the more complex your layout it, the more often it happens.

So what about changing the TOOLBAR code to get rid of the problem? I haven't yet found a solution; TOOLBAR mimics the toolbars used in MacOSX rather closely, including mouse over behaviour and the current solution using DETECT, is the only one, I've been able to find.

If you want to help, I can post a more technical note on how the FEEL code works. Leave your comments below.
