[UK-CONTEST] Data Programs

[Ray Hills]

Slightly off topic but has anyone any experience using MMVARI data software? 
It seems to have a close family resemblance to MMTTY but the associated 
explanatory text is far less comprehensive.  For example it claims to do 
"type ahead" but if I enter a few words into the TX box and then hit the TX 
button, it fails to send the final word.  If I just enter a callsign and hit 
the TX button it doesn't send it at all.  I can't find anything in the FAQs 
to explain this and - more importantly - sort it.  There may be other issues 
which haven't come to light yet as so far as I am just using it as a 
simulator on the PC.  Any ideas/help/suggestions welcome.
