try to replace "/home/pecan/devel/trunk/src/devel/codeblocks" with "/home/pecan/devel/trunk/src/devel/run.sh" in .mailcap
That actually works. But just once. Any further use of xdg-open on a .cbp file gets the following warning:
I'm about ready to give up on this. It's taken all day.
My gut tells me it's not going to work as well as the XP start command which opens any number of .cbp in one "already open" CB.
Oh well, win some, lose some.
Thanks for all the help.
