I can view all videos (although NOT in fullscreen), make SINGLE video-thumbnails with F3.
NOT working: Mark 2 or more videos and F3, scan folder/tree/disk: Result is "default" thumbnail.
Working: images thumbnails, even multiple.
Using Thumbsplus 10 SP1 4011, Win7 64bit 8Gb, multiple working codecs installed, admin.
Making all Thumbnails with Thumbsplus 7 works.
I am experienced, but this is not understood.
Thanks for help.
