Any plug-ins you might have running or not? There are a ton of them. At the office it seems to work fine, only on my home computer does this happen.

Just the default plug-ins and shockwave, none of which has anything to do with the spellchecker.=. the only extension I download and use is NoScript.

If your mouse operations are not working as they should, then I would check your mouse setups. I have not seen anything in preferences (tools - options for you winders users) that would indicate a setting for it.
