I have heard some reports that not having forms open in form view while
editing code does help to avoid corruption, so it is probably a good idea.
However the particular problem that I thought you might be experiencing
does, as far as I am aware, depend on the form having code running in the
Timer event procedure. If you don't have any code in that procedure, I think
it must be a different problem, but I'm not sure what. Unless someone else
has another suggestion, all I can suggest is to post back if it happens
again, with any additional information that you think may be relevant at the
time.

Making sure nothing is open in form view seemed to work. There may have
been a form that had a timer event on somewhere, but it was set at 0, but
I'm not sure that it was open. Oh well, it's working.
