Thanks for the replies.
Imago - unless I've misunderstood, you're referring to the standard windows resize function? I suppose there are some people who wouldn't be aware of this, so I understand why you've made the suggestion, but I am aware of this hence ".. I don't get windows resize handles.." - thanks for the suggestion though
Neeters - Thanks for your suggestion. I can't see anything that might cause this. Here's a screen cap of my prefs, can you see anything that I should adjust?
Does anyone else have any ideas?
I might just reinstall, maybe that will sort it out.
