I just flashed to v1.81.0 FINAL, Build 21009.1.6.0 with Manila (also tried build 20764). I'm having problems with the PTT button. I was using v1.50.1 prior to the flash and was able to use the PTT button out of the default configuration to bring up the HTCActionScreen. I was also able to use AE Button Plus to remap the PTT button for various single/multiple press functions, but I haven't been able to get the PTT button to work with the latest version of ROMeOS. I haven't been able to find a solution to this and haven't been able to successfully delete and remap the button in the registry.
Button 1 (Hold) in the buttons menu still refers to the PTT button, correct? Am I missing something?
