Applications malfunction Help!?

After a while of working on a project of mine, highlighting one word on the web will start from the bottom yo the word I highlighted, this is out of the blue and on the same site. Then when I go to click on Textedit the web browser hides and vice versa. Also in Text edit the highlight stick were I originally put it and wont budge (also cant seem to make the ~ symbol).
This happened twice both after freshly restart and reboot.

I am using a MacBook 2009 os x 10.5.8
I was going back and forth from web browser (Chrome) to Text edit to create a list for my word generator project.
I decided it would be faster if i use my tablet to assign buttons for convenience
[command C] to a button to copy the word from the web
[Shift ` enter] to another so that I can complete the code with a simple find search for ~ in the document
[option shift command Z] to paste the word copied from the web into Textedit with out the gross web font and background
I had both apps side by side so I could just use the pen to navigate easily. I know that's not what a tablet is for, but that doesn't stop it from being an awesome mouse when needed (would replace the touch pad with my tablet if I could)

This has never happened to me before I can't tell if it is Textedit hating my tablet after some time or that odd past code maybe...

Thank you for any help and if you need more info please let me know!

I found my answer through another forum ...
the hot key on my tablet with alt in it was getting stuck so it was constantly hitting alt with out me knowing!
