[WriteLog] %E Stopped Working

[David Fisher]

I am using WL 10.61E with the MMTTY plug-in on  Windows XP. The RTTY rig 
hr is the Icom 706MKIIG and the interface is the Rigblaster Plus. I run FSK.
This system has worked well in the past, but as I prepare for this 
weekend's RU, I find that my tx doesn't stop even though I have
%E in my messages. The only way I can get the rig from tx to rx is to 
manually hit the escape key and even then there is quite a lag until  tx 
stops.
This problem now exists with old contest formats that performed 
perfectly in the past with the existing  equipment.
Can you help?
