Interesting post.  We used 9.37A over the weekend in a two-computer 
multi-two situation at K6RC.  Station one was an FT1000D, station two 
was an FT1000MP.  Station two computer crashed dozens of times over the 
weekend in three different modes:

* the computer would just reboot itself and come back to a DOS prompt;
* the computer would freeze on the CT screen and not do anything at all, 
requiring manual rebooting; 
* the computer would give a QEMM error screen and require rebooting.

The computer connected to the 1000D suffered no such problems.  Both are 
486 DOS only machines with the network between two com ports.  This 
failure mode has not occurred before.  Unfortunately, like Dave, we 
upgraded CT at the same time the FT1000MP came into the station, so who 
knows what the cause is.

It didn't seem to be related to whether the affected computer or radio 
was transmitting at the time.  I don't think it was RF related at all, 
because I believe it happened also when neither radio was transmitting, 
but I am not 100% certain of that.

I had decided not to go to 9.39 due to all the comments about bandmap 
functions.

Interesting side note:  the computer and radio have been running by 
themselves all day with no crashes.  We will leave it alone for another 
day or two in this mode, then reconnect the network cable between the two 
computers and turn on the first station...
