I have a Gateway M280E, with 2 G RAM, 1.6 G processor and the optional graphics card. I'm running Vista - Enterprise edition. Recently, I have been having an ongoing problem with using the pen in tablet mode. Onscreen, when you touch the pen to screen, a large black box appears, about half-inch square. If I rotate the screen orientation, I can reduce the size of the "block" from 1/2" x 1/2" to about 1/2" long and about 5 pixels wide. I've reinstalled the video drivers, FinePoint and checked the BIOS per Gateway's suggestions. So far, nothing has helped. Anyone have this come up, or have any ideas why my computer is doing this?
