I know this issue has been around for a while. (Push a button on the screen and the one above activates) but I havn't noticed if a fix / patch has been made available yet.

Very annoying. I even made my buttons big and well seperate to try to avoid it but still happens.

So anyone have an update?????

Maybe a stupid question but have you done a screen calibration yet?

Yep. I have been led to believe from reading threads in the past that this is a known and common problem.

I ran into the mis-hit on occasion myself and chalked it up to my fat fingers. Then I had a brainstorm one day and put a screen protector like they make for cell phones on the MX300 and I find that the touchscreen is actually now a bit more accurate. Obviously I have no way of scientifically proving this theory and, in the interest of full disclosure, I have started selling the screen protectors but that's only because I think they work and no one else was selling them. Trust me when I say I ain't getting rich ;-)

Yea. I tried that myself and it did reduce the problem but it is still there.
