Hello, I've been really enjoying the usability and portability of the RtMidi library. However, everyonce in a while, the library causes my system (ubuntu edgy) to freeze. The system simply becomes unresponsive and a hard restart is required. This problem is very infrequent, but I would hate for it to come up during a performance. Any ideas about what may be going on?
