I love DrScheme like a child of mine (almost) but I have to say that I 
have experienced this on OS X. On a machine which never goes to sleep, 
it is not a problem. On my laptop, which I close for hours at a time, it 
is a problem on waking. DrScheme is very slow to respond, the disk can 
be heard clicking, and it can be cured by quitting it (once I get a menu 
to actually stay open) and immediately starting it up again. This has 
been the case with 299 through 301; I haven't enough experience with 
350, of course, to know if it persists there.

If there are any stats I can collect in order to diagnose the problem, 
please let me know. --PR
