Hi, I am using Aero Glass for 8.1 and have donated. The program no longer works for me, and I'm assuming it was a recent windows update. It seems to load ok, just provides no transparency: [2014-08-31 17:01:27][0x3C4:0xC88] Aero Glass for Win8.1 v1.2.5 x64 correctly loaded (C:\AeroGlass\dwmglass.dll). I am unsure of the best way to achieve getting support for this. Edit: as dhjohns stated below, it was because the Laptop was on battery.
