Just a shot in the dark here as I don't know what's causing this but the main computer on our office managers desk is now showing completely different "looks" on both her yahoo main and yahoo email pages and her facebook page looks completely different as well.  Her work apps...i.e. quickbooks, etc...all look the same as always.  We're thinking it is some key or key combo that was entered because she leaves her computer on over weekends and this weekend I KID YOU NOT a raccoon got in the building and caused a major cleanup condition.  And, apparently, one of it's last stops before exiting back through the ceiling tile from whence it came was to pitter patter around on her desk and computer keyboard.  Anywhoo...any help anyone can give regarding getting her screens back to the normal yahoo and facebook looks will be much appreciated.
 

LOL!
 
I don't have an asnwer to this, but I truly enjoy your stories Olpal.
 
(Bump!!)

Check to see if java is disabled in options.

I don't see that in my internet options...where, exactly??

Was his name Rocky?
 

We've got a raccoon that stops by occasionally to check out our water feature in the back yard.  I've named him Floyd - he's cool.
 
(No, he's not pink.)

You guys are sooo helpful. Thanks!!! :-)

Sorry.  But you did say a raccoon changed the PC settings (and, in our defense, you did post in the Coffee House).
 
Try F11 (full screen / back out of full screen).

Yup...that's what we're thinking.  She leaves her computer on overnight and on weekends and the little critter left tracks all over her desk.  The only thing that's changed is that her yahoo main screen, her yahoo email screen and her facebook screen all are completely different formats now.  Her app screens are still showing up the same.  It's some kind of internet view thingy I guess. 
 
Luckily the raccoon seems to have moved on as we have not had another nocturnal episode.
