I'm having problems with the front end also.

Right now I have the front end on a P200 notebook and I get almost
identical results, with a connect at 50% completed.
I was thinking along the same lines as to a possible cause, with the
program not recognizing the size of the keyspace being checked or
something similar.
Mine however does not try to connect after I log it off manually and
sits waiting at the end of a block until I again, then most of the time
it starts a new block, trying to log in on a 2^30 block at the same
point (13%).
If I am logged in already browsing before the progam attempts to find a
connection it does not disconnect, only when I start the connection when
it is waiting for one, and only some of the time.Also I'm wondering how
the keys per second are being measured, because I have been getting a 8
second first 2^22 block (around 1M key/sec), but now am getting 24
seconds (about 350k key/sec). Does it include the time it waits for a
connection when it calculates the key/sec? It slowly works its way to
approximately 950k key/s by the time it gets to a 2^30 block of keys.

On the positive side I like the fact that I'm only on the modem for 15
seconds every time it dials (except when I do it manually, when it takes
30-45 seconds). I was running freeDUM dialing in every twenty minutes
and using about 1:30 for every call. This method was using all of my
school alloted dial-up time per month just for DESchall!
