Yo Quidnunc
If I get anything like a fix, I will let you know.
I trust you will do likewise.
Never had a persisting problem with the software before.
Don't know where you're from, but if you are British, then the 'Sale of Goods Act' paragraph 2, section which mentions 'Goods not suitable for the purpose for which they are purchased' usually makes people pay attention.
Don't wish to turn unpleasant, but if I have to ....
By the way, when I enter WED (the editor), if I click 'new level', get a short flash of grid lines, but then thet disappear and 'zoom in' with the mouse just makes the pointer vanish until I release the button, when I find it has not moved. Also, if I enlarge (large screen view, top right of window) the top view, I get garbage but can see fragments of the level & grid lines?
I am using an emachine running XP, but tomorrow will try Vista!
Good luck
John
