Hi HL List.

I've found a partial workaround for the disappearig grid, when them are in a
TPageControl.

In the OnShow Event of the TPageControl write:

TIB_GridName.Visible := false;
TIB_GridName.Visible := true;

I think also:

TIB_GridName.Hide;
TIB_GridName.Show;

do the job, but I've not tested the latter.

This two lines of code repaint the grid.

Cleary this is a temporary and partial workaround, until Jason fix it.
