Hi,
I had the same problems using WL 10.40 and plug-in MMTTY 1.65. Computer is 
laptop, old CA 4500 200MHz. It has small LCD screen so I used to connect 
external monitor and cable mouse for contest. At the moment when program is 
finishing sending and going to receive MMTTY "froze up". It is strange, I 
observed such situation only on cq (operate key F2). Using another key (F5 with 
QRZ) repaired the MMTTY. Exactly the problem is in sound card so closing and 
opening MMTTY solved the problem, sound card is starting again.
I suppose the problem is on RF energy because without external monitor and mouse 
  everything was OK. Any way LCD screen and internal pad were very 
uncomfortable. We must build RF chokes on cabels coming to computer ports. So I 
wraped monitor and mouse cabels on ferrite cores (ring and rod) and since then 
no more "froze". The more windings the better.
