Bob,
If your second form isn't modal, then

a) the code that calls the second form doesn't stop at the calling line and resume after you leave the second form - it continues. And sometimes the error message concerns a value that is being returned from the second form but isn't found.

b) Is your first form calling 'Activate' method code when you return to it? Again, this happens when your second form isn't modal. The Activate code may be causing errors like Michelle mentioned.

Finally, if the second form IS modal, check all the return codes for NULLs
