[UK-CONTEST] N1MM Users Help please

[Ian G3WVG]

Hiya N1MM users.

I'm switching from WL to N1MM.  People tell me it's the way to go!

Everything seems pretty straightforward except for one quirky little thing.
When sending a CW CQ message from the F1 key any other key stroke I make
causes the message to stop. It's exactly as though I'd pressed the ESC key .
It doesn't happen with any of the other F key messages. 

As a slap-dash typist, I like to use my CQing time to make corrections, so
this is clearly a major disadvantage!!

Any suggestions as to what I'm doing wrong will be most welcome.

Thanks and 73 Ian G3WVG

 
ps I don't know if it's relevant but I'm using Winkey.
