After upgradeing to 10.2.4 I developed the modem disconnect issue on my tibook. I resolved that by swapping out a handful of ppp/modem related extensions for the 10.2.3 versions and that problem was solved.
Now, though, when I try to put the book to sleep, there is a long (maybe 20 second) pause before it goes to sleep. This is certainly preferable to the modem disconnects, but it would be nice not to have either problem.
Any thoughts?
