I just noticed that there is a bug report on the RedHat bugtracker about duplicate key presses detected in ir-keymap. Although I'm seeing a slightly different issue related to pushing one button then a different button, I thought maybe these problems could be related. I can't find the source code for ir-keymap online, but even if I could I don't know if I'd be able to analyze it since I'm not so great of a developer. Anyone have any suggestions?
