When I use the tab bar and try to adjust the tabs by clicking and dragging, the whole page disapears from view while I am moving the tab. As soon as I let go, the page reappears. Needles to say, this makes it very difficult to place the tabs where I want and have to move the tab "blind," release, look at where they type moved and try again.
The same problem does not seem to happen on an other Mac in the office. Both Macs are using the same OS (10.6.8) and the same version of InDesign (CC).
