I tried to simulate the problem by just viewing the report itself - and the problem didn't occur. It only occurs in exe :( And in exe there is no way to trace since the problem is happening in the report and there is no way to debug report (not in VFP6, at least).

Anyway, I'm guessing, that users of this application never ran into this problem and perhaps I should not try to fix it.
