I've noticed over the years that, for some unknown reason, java is
notoriously slow on some machines when doing large screen refreshes. I
have been unable to get to the bottom of this, but believe it relates to
some synch problem between javalibs delayed refresh and windows delayed
refresh.
Another suggestion is to make sure you have the HotSpot compiler
installed.

Hi Mark,
sorry that my tests didn't show any effect. All I can say at the moment
is that your problem is not a common problem. At work more than 20
colleagues of mine are using SQuirreL on different Windows and Linux
versions and no one ever complained about 3-4 seconds for switching
between sessions.
I have seen that with some look and feels switching session windows is
faster than with others but by far not in the range of seconds. You
might though try a Metal look and feel.
The last thing I can offer is that you try out the little test class
below. It opens a Desktop window with four child windows
(JInternalFrames) with editor panes on each. If you can reproduce the
lag on this example I'm pretty sure it is a problem with your system.
