Oh OK, I had not ever tested a supplied Easypano library skin.
Yes it 100% has a problem.
But to get around this i have modified the A1 skin which will work and let you get along with your project.
Download from here and unzip and place into your Easypano Tourweaver 7 skin directory.
The directory is located at:
C:\Program Files\Easypano\Tourweaver 7.00 Professional Edition\Skin (folder)
Once place into this folder, start up Tourweaver and it will be available from the skin library.
