Form flicker on open due to calculated text box based on subform

[votegop]

One tab on my tab control has three subforms on it. They work fine - no flicker. If I add calculated textboxes that perform calculations on the totals of the subforms (the textboxes are below the subforms on the tab control), I get one flicker per text box. ie: if I have four calculated textboxes, the tab control "blinks" four times on open.

Echo off does not help here.

Any ideas?

Nothing seemed to help. But I did find a solution, which I thought I'd post just in case it helps someone.

I simply made the text boxes on the main form unbound. I populate them with the data from the subform on open via code. No flicker. I also run a requery of the main form After Update on the subforms.
