I have a project I had some issues with (see my thread about Pan & Zoom) that I thought was resolved.  It was sort of.  Generally speaking, the movie plays as desired.  However, for some reason, many of my icons in the library window are green.  Some are fine, but most are a lime shade of green.  They all have green check marks since everything in my library is in my movie.  But for some reason, most - but not all - of the icons are green.  The others are normal thumbnails, which is how they used to be.  All of my jpegs have icons.  Anyone have any thoughts about this or know how to get my icons back?  Thanks.

Where the thumbnails always there? Green appears to be the default colour of a good clip which has yet to have a thumbnail or has lost it.

Have you tried refreshing the Library (there is an icon to do this on the bottom toolbar)?

Thanks for the suggestion.  I logged in this morning to try it and all of the icons were there, as they had been before.  I'm not sure I would have tried the refresh though.  I didn't know about that option but when I hovered over the icon, it said it would reload everything.  I assume that means I would have lost all of the edits I had already done to some of the clips.  Anyway, it appeared as though a reboot of Windows was the answer.  I had rebooted Pinnacle a number of times but that didn't get my icons back.  Thanks again for replying.

No, refreshing the library would have no effect at all in any saved projects or imported assets. I would not have suggested it if it was destructive.
