[RTTY] Keyboard Won't Send All the Letters?

[Bill Gaines]

I am having a very odd problem with my set up. I am using MMTTY V 1.65B. I have no problem programming any of the macro keys for transmitting. However when I go to keyboard a message to someone, the letter "P" will not show in either window. It simply will not transmit a "P". Now if I program a button to send a word with a "P" in it, such as my call, it works just fine. My keyboard works fine in PSK and all other functions, just not in MMTTY. Any suggestions to a rookie?
