I just downloaded unistalr. There doesn't appear to be any option to record an installation, like in some other installers, like for example, Total Unistall.
When you compare leftovers between uninstalr and Total Unistall, did you use the recording feature with Total Unistall when installing the program? Maybe there would be much fewer leftovers when using this option in software that supports it?
p.s. How do I edit the Title..?
