Some time ago, there was a change related to...  I think, something
about saving a change to a method in the debugger and/or a
highlighting issue?  Sorry, I can't even remember who it was; I'm
thinking Frank or Dave?

Whatever the issue was, the fix for it involved turning on some sort
of refresh stepping in the code pane.  This causes any text selection
to be lost in under two seconds, making it impossible to do code
interactions with the program being debugged.

Our love of developing in the debugger is being impeded.  How can we
get this fixed?
