DVI previewer gone haywire (fwd) -- solution??

[LMS journals]

Dear All

Thanks for various bits of support -- in the end I appear to have fixed it
by throwing away all temporary files (including internet ones), and then
dowloading the latest Acroread!  I had reckoned that I had less to lose by
trying to fix the acrobat stuff (and maybe messing up) first, than tinkering
around with DVIWindo.  Both these steps were in the suggestions on the Adobe
website, to cope with "screen freezes".

Which reminds me that on my previous computer (Windows 95), I had problems
with the screen "freezing", which I solved in the end by periodically
clearing the "tmp" folder.  Clearly, it has taken me the three years that
I've been using this one, to reach saturation point!  I guess the defrag
etc. was contemporaneous, rather than causal... I suspect the glut of temp
files caused the problems, which somehow also affected all the Acrobat stuff
as well as dviwindo.

This might be worth remembering, if anyone else hits the same problem, where
the screen "freezes" on an hourglass, and even Ctrl+Alt+Del doesn't work!
I'd be interested if anyone has a technical explanation that might help us
to pre-empt...

Thanks again

Sue
