I noticed a strange processor use when a small (i.e. smaller than the width of the displaying windows) flat panorama is displayed with krpano. The processors are continuously used at medium charge !!
To obtain this I just drop a flat panorama of 1600pxl large into MAKE PANO (FLAT) droplet.bat
The processor charge disappear when switching to an other Internet tab or when the width of the displaying windows become smaller than the pano size.
