Bart -
Porting your programs shouldn't be much of a problem, though you
will have to change your WIDGET_BASE() calls for top-level bases,
as well as calls to XMANAGER, in your widget programs. RSI introduced
the /NO_BLOCK keyword which gives you back your command-line after
registering a widget, and this necessitates the above changes. Also,
RSI changed the behavior of modal widgets, and moved this /MODAL
keyword. The changes are minimal, but if you have a large collection
of widget programs it may take some time to update them. Be aware
that until you do most of your widget programs won't work.
