Problems with audio

Camtasia is apparently not optimized for Mac OS X. I believe more care has been given to the Windows version (which has a few features not in the Mac version). In both 10.6.8 Snow Leopard and in 10.8.3 Mountain Lion I am having trouble with audio not being synchronized with the video. There is an approximate half-second offset which has to be adjusted by ungrouping audio and video tracks and carefully aligning them. Also, there is a poping sound every time I start recording a new segment. I have to eliminate these clipping peaks. Very annoying. Other than that, the app is fine.
