Returnil 2010 free vers 3.1.7779 Windows7 64 bit APC 1500RS ,software PowerChute v.2.1.1. All the rest is ok,but when I come back from suspension Powerchute APC software warns communications are off and battery is on, leaving icon in systemtray perennially signed by error henceforward. This happens both in admin/ltd accounts. The problem is there's no breakout of service as the UPS is working fine as usual from AC in spite of telling me its working from batteries, as there's no audio alarm of any sort from the UPS. If Returnil is off,no problem at all,whether in admin or limited. I filed an assistance request to APC,but I think its better to ask coldmoon,too,just in case he's a got any hint for this.
