mission control and safari window...

like the title says

in mission control, whatever safari window i just was in, comes up blue.
has anyone seen this? any idea of a fix?

 

answering my own post (what a nice guy i am!).

i reset everything in safari, rebooted. set things up again the way i want (home page, etc etc), and all is well..

not sure what happened tho...
but at least things are working (such as that is in Lion round 1...)
