I'm afraid it has nothing at all to do with 32 bit or 64.
In earlier versions of windows you would close the window by double clicking in the top lhs corner. I guess someone will say exactly when but it was probably 20 years ago. So no.
I've got used to that so sometimes I try to double click in the top left hand side and it doesn't work.
You can change your whole screen style to look like anything but if you think it will work with really old programs you'll be disappointed.
Send a PM to Edwin - he likes the same sort of look.
