You can fine tune the cutting points with the '4' and '6' keys (see MANUAL).
To have each sequence in a separate file you can set SplitEditedFiles in the
"Setup" menu.

I'm using SuSE 7.3 with kernel 2.4.10 (original from the CD) without any such problems
as you have described.

BTW: please wrap your lines...
