I use several cmdboxes from the Control Toolbox on a wsheet and each has an
Accelerator. They are laid out in 2 colums and 3 rows.

I've noticed that in design mode if I simply reposition a control its
accelerator underscore sometimes disappears and the only way to make this
visible again is to adjust the control height.

I am sure the height of each control is sufficient for the font size.
Curiously if I increase the control height then the underscore again
disappears.

The only way I can ensure the underscore remains visible in all cases is to
set a different height to the controls instead of all the same.

Can anyone throw any light on this and how can it be prevented?

T.I.A.
