[Trlog] Setup Question

[Bob Evans]

I've never run across this one before...
 
I'm setting up for CQWW and playing with Alt-D (I'm SOABLP) calls.  When
I hit the SPACEBAR to call the Alt-D loaded station, it switches to the
Alt rig, but waits for me to hit the ENTER key before sending my call.
I've never had this happen in any other contest that I can remember, but
I must have some setting incorrect.
 
Any suggestions?
