Web pages partly obscured.
This is a very irritating problem.
I sometimes get a whole page come up in only a 'corner' of the screen and not filling the lower part of the screen. Some writing is overlaid on other writing and in questions, which require number answers in a box, only half the box shows.
It seems to me that the right hand side of the screen, which appears to be empty, should be wider too.
This page and the whole of PPRuNe is OK and so are others.
