I Have had an interesting anomaly occur that others may be interested in.
A number of my saved Layouts have been used for several months.
I was having difficulty with long Layout loading times which evolved into extended Windows Not Responding issues.
I became suspicious of one of my saved Layouts, which I deleted and reconstructed after rebooting Logos.
Amazingly the problem disappeared. I then deleted and reconstructed the rest of my layouts. Logos now switches layouts much faster and seems to respond quicker all-around with no Windows Not Responding issues.
The program also syncs much faster now.
I Hope this helps someone.
