I'm running screen v. 3.07.04 on a pentium 90 on redhat 5.1, and
hitting control-A, control-A (switch to last window) takes forever
(about 5-10 seconds).
On Redhat 4.1 on a 386 it is about 100 times faster.
The redhat 5.1 install is a stock install of "everything" + all the
updates. I'm talking to the computer in text mode via telnet or
please email responses as well as posting for all:
