I have a report in Crystal 8.0 that will run for about 45 minutes and then show a formula up on the screen. When you check the formula, it says there are no errors, and the report shows up blank.

the formula is simple:
if isnull({vComm_Combo.AddressTwo}) then 'null' else 'blank'

The field exists just fine. Things aren't making sense. Where can I find out if future versions fixed this bug? Any ideas how to trouble shoot it?

Here is the bug article on Crystal:
