Strange behaviour of the UI

[ignominius]

I think I might have a partial answer. I think the behaviour is down to paging and video memory. I checked my disk space on my lap top and discovered I had very little disk space left. This meant that there was insufficient space for paging. Once I cleared out a few gigabytes of dead weight stuff off the computer and then restarted wings, the behaviour was still there but if I then minimised and then maxed the view, the whole screen became available to me to use for Wings. (This of course only happens with wings.)

So if anyone else ever has this problem - check disk and paging space and amend and try again.
