Big problem with compressed Safari screens.
Somehow I have developed a big problem where all my Safari screens have become compressed. Having selected a particular screen, it shows up as normal but 2 or 3 seconds later becomes severely compressed to about one eighth size.
I have tried the following ...
Cmd plus + Tempoarily brings the full size screen back, but as soon as I move to another screen it all reduces back.
Restart. Opens as reduced size.
Reload page Opens as reduced size
View > Zoom in Same temporary effect as Cmd plus +
Reset Safari No change
Empty cache No change
Getting desperate now ...
Download and apply a 10.6.8 combo update (which I already had anyway).
Repaired permissions. No change in situation.
Firefox is operating normally.
Would anyone have any ideas of what else I could try.
