I noticed this with Acronis True Image 7 and Drive SnapShot 1.32: If SoftLeds is running, and I begin imaging my active Windows partition, the imaging application effectively hangs. The imaging process sits there, doing almost nothing. As soon as SoftLeds is terminated, the imaging process takes right off normally.
This happened on my Windows XP Professional SP-1 system, with SoftLeds 1.6.
I've already notified the True Image support as well as the author of Drive SnapShot.
