Touchpad touchscreen problems (erratic behavior/not responding correctly/etc) temporary solution.

Question

I bought a HP Touchpad about a month or two after it came out. It worked pretty much as you'd expect it to until some time ago. I started getting a problem where the screen would go crazy and not respond correctly to my touch inputs. Web pages would jump all over the place, cards would zoom out, etc, in other words, they would behave erratically. After some testing I noticed that certain areas  of the touchscreen would NOT respond at all to inputs while others would make the screen go crazy like I mentioned previously. I looked for information on the web to see if other people where having the same problem and found reports of the same behavior. Unfortunately there where no solutions offered. At that point I tried turning on and off the Touchpad which did not resolve the problem. My next step was to try to reinstall the OS with WebOS Doctor, but I read a post where the user reported similar behavior and reinstalling with WebOS Doctor didn't fix the problem. Needless to say I was bummed out since I figured it was a hardware problem with the touchscreen. After more testing I found a temporary solution to the problem which seems to suggest that the probem could be software. The solution when you get the problem is to hold down the power button and the home button at the same time and keep them pressed until the screen shuts down and the touchpad restarts. Once the OS comes back up it works like it is supposed to until you get the next episode of screen epilepsy. At that point you need to do the procedure again and it will fix the problem temporarily. Usually the fix lasts for a few days in my case. The fix also solves other problems I have with the touchpad. Problems like, videos not playing fluidly or freezing every few seconds although the sound plays fine (youtube), sound gets messed up (sounds are played in a robot like pitch), and others. If anybody has questions or other suggestions let me know, I will answer the as best as I can.

I think the YouTube and sound problems are separate from the other erratic behaviour.  Recently my touchpad won't play YouTube videos beyond certain points, starting a few seconds in possibly due to the advertising pop-ups - I can skip forwards, but that means I miss crucial parts.  My sound also goes 'robot-like' until a reboot, which is incredibly annoying!  Your touchscreen problems may be specific to your device - try going to Device Info / Diagnostics and see if that tells you anything.
