While operating pj7/w1cx when my log reached about 800 qso's, the mmtty screen 
on the computer would freeze and I had to  restart the computer to continue. It 
happened repeatedly until the contest was over. 
I have been able to recreate this with no rf in the shack at all. 
I have established that it was the result of using Writelog-Rttyrite--the 
plugin--mmtty all at once. I have used Writelog (sometimes with rttyrite) with 
very high rates and large logs in the past and I am convinced that it is not 
the problem--Writelog has always worked flawlessly. Mmtty states clearly that 
it uses a lot of resources and I can freeze it merely by switching to FIR 
detection and simulating a contact when there are 1500+ qso's in the Writelog 
log. 
My only point in posting this is that before going to some far away location 
expecting to run a sound card demodulator, try out the whole setup first with a 
big log file in place. My Hal DXP 38 is going next time. (That's optimism!)
Details: the computer is a Dell Inspirion 4000, 550 hHz, 128 m of ram, startup 
minimized. mmtty: priority, higher and the echo option turned off. Running WL 
v10.38 and mmtty 1.62.
I hope this helps someone.
Regards, Loyd, w1cx
