[CQ-Contest] RTTY Window has disappeared

[Carol Richards]

I was operating the WAE-RTTY contest and everything was fine until 
suddenly my digital window disappeared The rtty engine appears, the mode 
is set for rtty. I am using MMTTY which works fine as a stand alone. I 
know I am generating tones because my interface is working fine. The 
keyboard behaves normally and the function keys are fine. The digital 
window is not hidden.


What happened?
