Multiple playback bugs

Hi, Am I the only one experiencing these weird bugs in STP 2?

I'm in Tiger 10.4.11 BTW. The bugs are as follows:

I use STP to ADR material sent from FCP. I use the loop & multitake function.

1-Sometimes during a looping playback, the video loops but the audio will keep going to the next clip, the one after that etc. Simply pressing stop/play fixes it (although it can come back later).
2-Sometimes the playback volume rises inexplicably to its maximum and remains very high (my clients with earphones are thrilled). Again, stop/play solves it.

3-Sometimes when I press record, an additional track appears and STP records both on my currently selected/armed track and to the new one. If I stop and delete this new track, it creates ANOTHER one next recording etc. The only way to solve this that I could find is to close STP and reopen it.

Am I the only one affected by these bugs?
