Yes the setup of my monitors on my two workstations are identical...
Yesterday I set up icons within fences in Fences 5. This morning, I'm remoted in to that workstation, and the icons are exactly as I left them I then sent a ctrl-alt-del command and restarted that desktop remotely. When it came back up, the icons are still within the fences. So I cannot replicate the issue in Fences 5.
Possibly the issue is resolved.
One more question regarding licensing. I only recently purchased Fences 4, and never could get it to run correctly. While we were working on this issue, Fences 5 was released. Since I licensed and paid for, but never used Fences 4 - can you extend that license to Fences 5?
