Minimal hassles with DOS CT 9.92-001 in the ARRL 10 m.
This is on a single PC, logged on to Packet Cluster. No network.

Only one comment: CT stopped responding to keystrokes at one point 
Although the ALT-sequences still worked, I couldn't type a callsign.
I was fiddling with packet at the time (ALT-T).
This is later on in the contest. A case of the speed wobbles?  At that 
point I re-booted.

In the CQWW-CW we had several crashes, which affected the BIOS clock 
on a 3 PC network. Same version of CT, same OS.

With regards to slow response: try disabling master callsign checking. 
This is done with a command-line switch, or possibly by renaming the 
master callsign file. 

If you have a really large master.dat, the look-up slows things down.  
If this is the cause, you may find that certain prefixes, of which 
there are a lot of in the master.dat, cause longer delays than other 


P5 = no QRX
JH = long QRX

Another suggestion: incrementally remove memory drivers and device 
drivers from config.sys and check CT responsiveness. You may need 
disk caching to speed things up. Perhaps you are better off not using 
disk caching if you don't have to.

Hope this helps...
