I'm pretty sure I am.  Unfortunately, after I saved the project, exited and came
back, I can no longer replicate it.  Don't worry, it will come back relatively
soon and I'll see what I can report.

Best I can tell, the problem comes up when I load a different window.  Sometimes
(and I haven't identified exactly when) the loading of a different window causes
one routine or another to disappear.  Once that has happened, if I don't
immediately exit I can find the problem like the one I just reported happening. 
Of course, to make the system run, I have to restore the lost routine.  That just
leaves me in the inconsistent state that allows the above described error,
though.

For example, I have three windows (which you know from before).  When switching
from the main window to my secondary window, it will sometimes come up showing
the code for my main window's onOpen routine in the onOpen routine for the
secondary window.  Complete with the first line (procedure ....) and the last
line (set handler).  When that happens, I can go into a backup and get the code
for the secondary window's onOpen routine and the IDE can create an exw which
will run (not necessarily properly, but it will run).  I've got enough going on
in my project now that for it to run means that almost everything is in the right
place.  However, when a crash takes place I get strange results, as reported
above.

Of course, the "solution" is to exit immediately after restoring the obliterated
code and come back in, which should at least eliminate the inconsistent state. 
But I want to keep the inconsistent state around long enough to give you enough
information to try and figure out what is going on!  A definite catch 22, huh?

BTW, I couldn't find "CODE EDITOR MENU OPTIONS".  Did you mean "Options
Configure IDE"?

Thanks
