Ok I've no clue what is going on with version 3.272 but here's what I can tell you..
I had version 3.265, then tried to install 3.272.. all my settings seemed to disappear. (No big deal easy enough to fix).
I went to TV shows --> folders first.. added my root... then hit Add folders from Roots.
The show folders appeared rather quickly, but I couldn't do anything else.. every time I'd click on the MC window, the PC would beep as if the app was frozen. Trying to move away from the app and it would take focus right back. There was no popup or visual indicator that it was doing anything, it just seemed frozen.
I had a phone call and after about 10 minutes I noticed a popup saying "changes saved".... no clue what it was doing but obviously it was 'working' on something.
2nd Issue is the background scraping... great idea.. poor implementation. It seems that while it does indeed scrape things in the 'background' all that really means to MC is that it is not giving the user any sort of feedback that it's scraping.. no line at the bottom like it used to or anything... the problem is that it keeps taking FOCUS whenever it updates itself.. so you can't work on another window on your PC at all since it seems to update something about every 2-4 seconds... trying to write this message itself was hell
I'm sure that will be fixed eventually, but thought you should know..
