I tracked down the problem to the procedure
TIB_CustomGrid.GetCellDisplayText(
I replaced this function with an older version. (I found an 4.2Ib
Version on my harddisk) and the behaviour is as it should be.
The problem is, that I don´t understand the changes between the 2
versions and I don´t want to downgrade this procedure. Perhaps the
older version has another error?

Jason, can I send you the 2 versions to check the differences. Or
should I post it here?

regards
Oliver
