I gave up on Fences a couple of years ago due to a bug that causes two UAC prompts to pop up every time I boot my computer. If I deny them both, Fences still seems to run OK. Maybe there is functionality that is missing because I deny them. If there is, I haven't noticed.
Anyway, I installed the Fences 3.1 beta hoping that this issue was resolved, but unfortunately it was not. It would be really nice if this could be fixed.
I have tried using the "purge_fences.bat" file as detailed in this post, but it did not help.
I really love the functionality that Fences provides, but this UAC prompt issue has forced me to live without it.
