on my W7 x64 machine SparkWindows 2.0.5719.0 causes 17% svchost constant usage. Digging deeper, this svchost instance runs several processes and one of them is the Windows Desktop Manager UxSms responsible for the Aero GUI overlays, i believe:
- stopping UxSms causes SparkWindows to spike to 25%/1 full (virtual) core
- killing SparkWindows (before stopping UxSms or either with it running) causes cpu getting back to normal background levels
It clearly indicates issues in the way the Spark exe interworks with the OS Windows Desktop Manager/Aero process.
Spark exe itself anyway consumes 5-15% cpu at rest, just after svchost instance above.
Anyone saw this? I hav McAfee MCShield too, for what it matters.
