FM 10 Pro Advanced and Windows 7
If you click and drag an object to move it in Layout mode when using FM 10 Advanced in Windows 7 the screen will flash black for half a second before returning to normal. This only happens when you select the object to drag it to a new location. If you select the object and move it with the curser keys the screen does not flash.
A couple of other customers have reported something similar with FileMaker Pro 10 and Windows 7. I have forwarded your information to our Development and Software Quality Assurance (Testing) departments for review and confirmation. When additional information becomes available, I will let you know.
