I just learned to use the pencil tool on Soundforge 8. The pencil tool was actually a function way back on Soundforge 4.5 believe it or not. I had a source with probably 400 or more pops,clicks,zaps, you name it and I drew threw them all. I order to use the pencil tool, you first have to zoom into 2:1 or 1:1 (keep clicking the + at the bottom right) and the pencil tool icon will light up to use otherwise it's ghosted out. If the pop is only one channel and you get tired of drawing, you can also just copy over the good channel if the spike is minimal. You're only dealing with a millisecond and there's no damaging the good audio portion of the wav. Audio Restoration is not recommended for clicks since it doesn't completely remove all the clicks like drawing through it with the pencil will. I've tried both ways and the pencil tool is just amazing.
