I have a weird problem that I'm afraid might be a Windows problem as opposed to Eclipse, but the first place I noticed it was in Eclipse, so I thought I'd see if anyone had had the same thing.  One time when I had a text file open, the cursor suddenly started moving from left to right very quickly, through every line in the document.  It was as if I were in Hyperkeys and holding down the L key continuously, but I think it was moving even way faster than that.  Nothing I did would make it stop, and I ended up shutting the computer down by holding down the power key. 

Then another time, I was in my desktop, and every icon in my desktop started lighting up one at a time, as if I were going through and clicking each one at a time.  Again, nothing I could do to stop it.  Someone suggested checking Sticky Keys in Windows, so I did, but it's not even turned on.  I am running Windows Vista Ultimate.  Can anyone help?
