How to cure video panning?

[pupquest]

Perhaps someone has already encounterd this and can point me in the right direction. Xvesa 1024x768 drives output to my monitor fine (which BTW, supports 1280x1024 natively). But if I choose 1280x1024 through the Xvesa wizard, puppy does indeed create a 1280x1024 desktop but it will only display the upper left 1024x768 of the desktop on my monitor. I can't even pan over to the right or the bottom to see the task bar. Appreciate any help. Puppy is really terrific... I'm just trying to figure out a satisfactory video output configuration. Also, I haven't given up on the Xorg path, I'm just having to use Xvesa in the meantime and would like to have a little more screen real estate.
Thanks,
Martin
