Hello, I have tried to run the Maple 10 program on my Toshiba Tecra M4 TabletPC and it runs fine until I go to Tablet Mode. The only part of the program that will run in Tablet mode is the Classic Worksheet. The symptoms are that the windows that appear in say the documentation mode (in Tablet Mode) come up but are solid gray. The program seems to hang. Now what I mean by "Tablet Mode" is that you flip the touchscreen around and lock it on top of the keyboard. This cause the display to go from a horizontal presentation to a vertical sheet of paper presentation. Regards, Dave
