Sorry to hear you are having issues. Need to understand something.
1) Fences Desktop pages 1 and 2. Is both setup on monitor 1 with same items? i.e Icon1 in Desktop page 1 also appear in Desktop page 2?
2) Also need to know system setup.
I) Windows version (Please use Winver.exe for full version numbers)
II) Fences version.
III) Monitor setup : Resolution on each monitor, scaling applied if any, connection type HDMI/DP/DVI/VGA/USB etc.
