I have a TIB_Grid connected to a TIB_Query displaying some records
from a query. If the screen is left idle for a period of time (4-5
minutes) the data colums are blanked out leaving only the column
headings. The query has to be re-executed to restore the display.

Does anyone know what is causing this? It doesn't seem to happen
with a TBGrid and TIBOQuery combination.

I have checked the properties of both components and there doesn't
seem to be any settings that might be responsible. The CallBackInt
property is set to -1.

Any help would be appreciated.

Regards

Bob
