I have the same issue with RMC 4.4.5 using IE9, FF10, and GC v22. If I try to use the audio recorder it goes crazy with beeping and chopping the music so fast it sounds like an echo. Clicking the stop button and trying to close the program would not work to end the chaos! I had to start windows task manager and kill the process to make it stop. In the RMC recording folder it shows repeated numbered .wav files (325 of them!), each 8.04 kb. YouTube is only trouble spot currently.
