Hi Wes

Thanks for replying.

I fixed it after posting the message. However, the problem was caused dependent on the user status who logged on. Certain users run startup programs. If the startup found certain conditions, a relationship was established that should have been cleaned up after the process, but wasn't (guilty) <s>. The process that fell over used files for new relationships that were involved in the hungover startup relationship. When that was broke, the data type mismatch occured as you predicted (what a Guy) <g>.

So another part of the system was fixed as a result thereof. If I hadn't investigated the relationship that I saw in the View window, I would still be scratching my head, had you not replied.

Thanks again Wes.
