I have ver 2.2.0 (001), running on Ubuntu 16, with a Winkeyer. Since the upgrade to the latest version, in CW Type, letter mode it sends each character twice, as in: CCQQ CCQQ. The "word mode, first word in letter mode" does not do this. I have used it for a long time (thank you!) and it did not do this until just now.
I tried powering the keyer off and on again, and getting out of CQRLOG and back in again but no change. Any suggestions appreciated.
