After the 4.78 upgrade it seems if the 2Web interface has poor performance. It will seem to hang for a couple of seconds then work ok for a minute or so then hang again. It is if something is preventing the screen refresh. No searches are being performed, album cover lookups are not being done and it could even be in the middle of the song so a song change is not causing it. I also noticed in 4.78 that the system Page File usage seems to stay at a consistent high number 1.82 GB where before it would fluctuate up and down. On the plus side at the console interface everything seems a little faster.
