Camtasia Seek Bar Precision and Preview are not Lockstep

From time to time when working on projects in Camtasia I find that the precision of the seek bar is questionable.  I am not sure if this is due to a buffering problem, but typically when you move the seek bar in a preview program like Camtasia, the video preview will move to that precise position.  If you slide gently left or right, one would expect the preview to change as well.  This is not always the case and I am curious about the implementation of the seek bar and the video preview on windows.  It is incredibly frustrating when I am trying to make certain that audio and video are lined up because they do not increment equally and are not coerced into moving in a "lockstep" fashion, or in concert with one another.  Rather, sometimes the video is ahead, sometimes the audio is ahead, and in large projects that have many assets this error-prone operation is compounded, sometimes so much that I must simply start from a fresh project.  Is this something specific to Windows that allows the seek bar and the video preview to be out of sync?

I cannot say I've experienced the issue you describe; but will point out some things to consider:
1. Is your computer hardware up to the task? (i.e., enough memory, resources, etc. ) or is your system underpowered or questionable? This is probably not the issue but we have to ask :)
2. Detach the preview window from the canvas and (ideally) have it display in a separate monitor at 100%. I've noticed when the preview window is in its default location and displaying at 30 or 40% of its normal size, things will become 'imperfect' as you describe. 
3. For super-precise editing of timing, make sure you are viewing your timeline as 'zoomed in' as possible by moving it all the way to the right (+) side 

4. Are you aware you can 'frame by frame' your production using the arrow keys to the left of the main 'play' arrow? I find 'frame by framing' to work fairly well and consistently when performing precise edits and that the preview ends up being (fairly) identical to the final produced version. Hope this helps!
