Hi JIm.

Actually you were quite helpful. The suggestion to gradually remove stuff from the form until the problem went away was good. I elected to go the other route, i.e. create a new form and gradually add stuff until the problem reappears.

Yep - just 2 sides of the same coin. I'm glad you are getting things sorted out.

Now to add more stuff.

Please report back and let me know when you find out what caused the problem in the first place. Should be interesting to see what it was.
