Here is a workaround: In the table's rule validation put a call to a stored procedure instead of the rule itself.

> I insert programmatically Table's Rule Validation. It could be very long string (more than 255 characters). When I open table for modify structure, go to Table Tab and click on ... button next to Table Rule (expression builder) VFP 6.0 tries to do something and then I have Fatal Error. And even worse - after that I've tried to start IE and it says "not enough memory..." (we bought a new computer 2 weeks ago - 433MHz, 64MB RAM, BTW, I am not satisfied - it seems like some problems with hardwire), so I had to restart my computer.
