I found that going to MSCONFIG and removing NMBgMonitor (which is a Nero Essentials component) from Startup, removed the WMS Idle failing to quit. More importantly removing that Nero file from startup, allowed Windows XP to shutdown ten times faster. I have removed Nero from my computer and it runs perfectly now. Perhaps only a corrupted file, who knows, but bye bye WMS Idle.
Thank you so much for putting such a clear and exact answer to my question of ” WMS not Responding” I followed your instructions and the nag is gone and I find it help speed up my shut down time. You do know your stuff,thanks again ..EBB Nfld.
