Cons
Con No image scalling
This may not seem like much, but if your screen resolution is smaller than your picture, then you will only see a small part of the picture. And although you can move around the picture, it is impossible to zoom in and out.
Con Slugish single core CPU performance
No multi core, and only single core cpu usage, means that the software does not perform tasks at smooth speeds when textures get anywhere over 512x512 (depending on the cpu in use).
Con Abandoned
This software has not been updated in years.
