Hi Layback Bear
No other media players installed. The PC is used as a media centre primarily, along with a bit of photo/video editing so the only things I have installed are:
Commodo Internet Security (have also tried an install with McAfee instead)
MS Office 2010
Adobe Master Collection CS5
Shark 007 Codec pack (have also tried and install with K-Lite instead)
All seems to work fine until the full media library has been built, then after the next reboot, the controls have gone. tried several ways of do it, i.e. building the media library before installing anything else, installing everything else first then building media library.
I have had this set up for years, with all of the same software (I have even tried installing the older versions of all of the software), then all of a sudden, a few weeks ago media player breaks, and cant seem to resolve it).
