Rated 4 out of 5 stars
Works Fine in FireFox 3.6.13 on Windows XP sp2
I thought I would mention that as I see a post suggesting there could be a problem with FF v3.6.12
I would add that I assume the Windows help reader is dependent on Internet Explorer, & I would prefer a solution not dependent on IE that in itself is a good reason to use this reader.
An additional feature I would like would be the ability to open a .chm file by right clicking it from within Windows. ( it does not by default do that).
