It does it in Playing now, but it does not jump to media library, the page reloads at times causing skips in the music, but it does it constantly in Media Library, it does it in burn, it does it in playlist. Incidently, I did a virus scan, none found, I have also turned off any other application running and still the same result. I have had Media Center on this computer from an Early Beta stage, never had any kind of major problem until I updated around version .315 or .316
When I go to CD, DVD, & Handhelds, with nothing in the drives, a constant analysing devices popup comes up in rapid secession. with a cd in the drive, it works perfectly. Hmm, now that is an odd discovery, while a cd is playing, I can switch the screen to Media Library, and the sorting has stopped completely. Take the cd out, It starts all over again with the analysing devices, and the sorting on Media Library. I put the CD back in let it load, the analysing stopped, went to Media Library and the sorting has stopped. I have now done this five times with the same result.
