I updated MB to 3.3.7310 a few weeks ago. I am running W7, so no store version here.
Anyway, I noted these strange bugs or issues when scrolling through songs quite rapidly. When I look at upcoming tracks I see for example songs, A, B, C, D, and E. A track is playing, I hit skip next up is B, but MB skips song B and shows that it is playing C. Yet I can hear both songs B and C playing. I can reproduce this issue consistently by just skipping tracks.
There is also a second issue which occurs when also skipping tracks repeatedly. An error pop-up pops up, but I cannot read it as MB freezes and the Windows "MusicBee has stopped working" error opens.
This is the latest error in the log, but if I remember correctly my GPU driver crashed causing MB to close. Nevertheless, I don't remember seeing the errors I'm describing in this post occuring at the time mentioned in the following error message.

Edit: Just as I posted and continued to try and replicate the freezing bug, I did manage to get an error about the "sound output locking up". This could be the error popup that I mentioned earlier, as the popup window is roughly the same size. However, when MB freezes "hard" the error popup isn't "loaded" so I cannot read it.
Also as further info on the first bug (two tracks at the same time), if I press previous track button, B-song will play (as in the right track after song A).
