I'm having that problem, for some reason my pointer gets big, like when i hold my windows ie for example it gets small again, upon release it gets bigger, i'm not sure why it does that! it is rather annoying.

what did you do to fix the problem
ALSO btw, on this site the submit button has "submit query on top of "submit" black and white respectively, is that a bug of this site, or my windows?
