On R2010a I've been experiencing very slow updates of Matlab's
windows, such as figure windows or the Matlab desktop. It can take up
to 5 minutes to update the windows following what seem like simple
commands (plotting, loading files, etc). Until the update happens,
the Matlab windows contain a snapshot of any other program's windows
that happen to be open under them, such as Outlook or my web browser.
Then when the refresh happens, I once again see the Matlab figure,
Matlab desktop, etc. The problem occurs even if I restart Matlab or
my computer and if I have nothing else running besides Matlab. I do
have a mounted drive on my Matlab path that can be very slow to
access.
Any idea what is going wrong?

That drive could be causing the problem, as Matlab would be wanting to search
that drive to determine whether you have a function shadowing the built-in
functions. You might want to put that drive last in your matlab path, or you
might want to use liberal doses of the builtin() function call.
