Firefox is messed up pretty bad (shown on the RH side below) - note lack of all the gray boxes. Other sites are even worse.
Yet, Chrome (on the left) seems to work fine.
Yet again, MS Outlook seems messed up a little bit (as tho it is running in some sort of reduced resolution or low color bit mode).
other apps seem ok - Word, Excel, iTunes...
I can't seem to find anything in the Firefox Options that is wrong (and the secret squirrel, hidden options on a web page looking thingie are beyond my ability to decipher).
