Missing views on drawings

There are several of us here that have, what seems like, abug with 2009.
We will open a drawing and one and sometimes two of the projectedviews are missing.
You can mouse over where you know they are, and red lines willappear, but no view will show.
We have found 2 work arounds, but not having the problem would bebetter.
One way is to open the assembly, rebuild the assembly, and closeit. The views are now showing.
The other way is to RMB on the section cut line, choose editsketch, and then close the sketch. Again, the view is not showing.
Has anyone else had this problem and do you know how to prevent itfrom happening in the first place?
Thanks so much for your help.
