This is really frustrating!
I've just designed 3 Tab forms, each of which opens a subform. No probs with the subforms. But for some strange reason, whenever I click on the first tab, the Forms Toolbar disappears and when I click on each of the other 2 Tabs the Toolbar re-appears! I've tried repositioning the toolbar at the top of the screen, at the bottom and also vertically at the left margin. Same thing keeps happening. If this makes any sense, it seems the toolbar is in someway "attached" to the first Tab form. Any ideas what I could have done wrong?
