I will try this Rich! I am running Vista Business, but after Christmas I will have time to delve into more exploratory methodology.
Thank you for sticking with me on this. I solved my hubby's problem by getting him another X61 tablet and switching out the hard drives so he could keep working. He uses this machine for his work. In fact he gets panic stricken if it doesn't work! So I get the old one and that is why I get to explore its possibilities...

Also, it helped to eliminate any software issue questions I had, because both hard drives, both running Vista business, worked in the newer machine without a hitch. The multi-touch worked great on the newer machine with either one of the hard drives installed. I just got to do these tests this last weekend. I also made very sure that I have all the latest and greatest drivers installed from Lenovo and updated Windows Vista. At one point, I also installed Windows 7 on this machine on a different hard drive to see if that had any affect and it did not. I also tried the drivers from Bamboo Fun and that is when I got the error message that there is no tablet installed on this system(I had uninstalled the previous Wacom drivers). I have not had the opportunity to take the screen apart to see if the cable had become unplugged, tho with the sticky pad that glued it down, I can't see how. But I have my fingers crossed that maybe that is it.

I thought I would also check the fuses, a good exercise for me. Plus I need to replace the cpu fan, or put a little oil on it, it is making a bit of noise.
I found a G4 digitizer on ebay the other day, almost was tempted to get it, but remembered you saying that the cabling was not the same and I sure did not want to have to replace that again!
