(I'll keep this in the same thread for now)
Actually *typing* within the FreeWin window is behaving very strangely ...
the cursor is hardly moving, or moving erratically, and my typed text is
mostly coming out backwards?
I enter <return> a couple of times and the cursor returns to the top of the
screen etc. ... any thoughts?
Thanks
J^n
