hello Jason,

I have also spent hours on this problems, achieving only a big headache
:-) I have used conditional breakpoints, but at a certain point into
execution, I have lost myself somewhere in the intricacy of the VCL. I
hope that someone else would be so kind to give a look at this problem.
I can't believe that there is not anybody here using contextual help on
an TIB_Grid :-)

Regards
Salvatore
