Losing compile and save options

I have a co-worker who has periodic problems in WDSC 7.0.0.8 . She'll
debug a program and when she finishes, she can no longer save or compile
the member--the compile icon and the menu bar options are greyed out. The
icon for saving the file is still there, but the asterisk doesn't go away
and the member is not updated on IBM i. The only way to fully recover
functionality is to close down WDSC and restart. Of course when you do
this, you can't undo changes, etc. I can't find anything wrong with her
configuration.

Here's a excerpt from the log file around one time of the error:

Does anyone have any ideas of what's going wrong or more importantly, how
to fix it?
