i use pngshot on raze's recommendation and find it terrific for what it is.
i really don't have much of a delay (freeze) in action however and suspect that some of that is system dependant.
all the shots you see in these forums (of mine) were taekn with png.
raze - i've got a couple 30 gig maxtor HDs sitting around (collecting dust). i'm thinking i should send you one! those remaining gigs of yours must be about gone! <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
