Fences don't fade in/out properly after adding second monitor

Hi, I am interested in getting Fences Pro, but I need to resolve this minor problem first. 

Fences was working great and fading in/out great with one monitor. When I added a second monitor, I was fiddling for a while with the Nvidia control panel to see if I could make one large display by using the custom resolution function, but that didn't work out. Anyhow, I am using an extended desktop now and my fences are on the primary monitor, which is fine.

But, when I double click on the desktop, the fences will only partially fade in and then if I double click more, then the fences sort of finish, but as I pan thru them with my cursor, the Icons and fences start being erased under the cursor. If I double click jut the right amount of times, then the fences can be made to finally completely disappear and then are completely displayed and react normally. I removed the program completely and reinstalled and got the same issue.

I don't know if it is just because I am running dual monitors, or fences got confused or corrupted when I was fiddling with resolutions. Any suggestions? I could try temporarily disabling the second monitor and testing it. Also, I was thinking that something got confused with fences in the registry or some other place where, when I totally uninstalled fences, something was still lingering.

 OK, I just disabled the second monitor in Windows and Fences wroked just fine again, nice fade in/out, etc. so, I guess it is a bit finicky with dual monitors. If there is a solution, that would be great, if not, I will just continue where I am at at the moment and not purchase it.
