Thanks Marty.

I may have resolved the problem. I recompiled the code with the 'rebuild all' selection off. Prior to this I was rebuilding all the files every time I recompiled. Now it works OK. I did not see any reference to the error occurring during compilation in the MSDN articles. Maybe this is a new one.
