Thanks for your message but I've just this minute checked out what you have said but no, it does NOT work. The section of the dialogue in your reply shows a full size number -- both PCs here that are on Windows 11 show what looks more like a superscript number and it appears to switch only between 0 and 1. Currently, as I have said before, the ONLY way I can adjust the spacing is via Regedit and the SnapPadding parameter.
Since I purchased a pack of five upgrades, I installed Fences 5 on my husbands PC yesterday and since he is still on Windows 10 I had no problems adjusting the inter-fence spacing. Because I and a spare PC are both on Windows 11 I have to adjust the inter-fence spacing using the Registry.
Sorry to be the barer of such news but I can only tell you how it affect us here.
