New Environmental Variable. Variables not scoped with 'my' in breakpoint expressions were not being evalled properly. Evaluation of certain 'CODE' ref variables caused the debugger to fail and exit. You can hide a large tree in the expression window by double clicking it. Double clicking again will bring it back.
Menus are now 'traditionally' styled in look and feel.
Fixed a problem where you would 'exit' if you entered the same expression twice. Now you get an alert. Background of stopped line text is now 'blue' to increase visibility. Configuration of stopped text has been moved up to the top of the file to allow for easier customization. Fixed a bug where you would lose your breakpoints when manually switching between files.
