I've been running version 312.1 for 4 hours now without any issues. The preview problem has cleared up completely and things are back to working as good as ever. Thanks John and Thanks Tracker for building excellent software!

Hey John,

My apologies! I see that it is the 312.0 build, I'll attempt to upgrade and report if the issues persist or go away.

Thanks,

Richard

I'm also having the same issue with the prevhost no longer displaying a preview in windows explorer.
