Hi Bob,

Originally I couldn't get it to crash until I follow specific steps below:
1. Open Test.prg
2. Make any modification to code
3. Close the PRG by clicking on the X button and confirm save.
4. Open Test.prg again
5. Type oTest. and pick SetRelationalExpression from the Intellisense list
6. Type (
7. At this point VFP hangs and after a while generates C5 error

I couldn't get it to crash if in step 3 I close test.prg any other way.

>Hmm, that's odd. I've tried it on a few computers at work and on my home computers, all of which causes a C5. One of my home computers is basically VFP 9.0 installed w/o any special environment settings and it C5's.

>If I can ask a quick question, you were able to see the SetRelationalExpression method and press the “(“ key and you didn’t get a C5 Error, right? (I wouldn’t ask this silly question if I hadn’t tried this on several machine with the same results, oh and I want to make sure you could see this method)

>Another quick question, could it be another none VFP environment issues?
