Thanks. No huge hurry. I have 07 running on my VL 6.0 xfce ibm t42. I looked in my src and the 4pane directory (4pane-0.7.0) is there, plus two files, as follows:
4pane-0.7.0.tar.gz
4pane-0.7.0-13.0-i486-1.tgz
the gz and tgz files are dated only 3 seconds apart and the directory is dated less than a minute later.

I've worked out what the install is doing, though I have no idea
why its doing it. Part of the problem lies with Vector - by default there is a symlink from /usr/doc to /usr/share/doc, which is helping to cause the problem. The rest of the problem is in symlinks created by the 4Pane install process - which the pkgtools remove at the end of the build, then add into the 'doinst.sh' that is packed with the rest. What that does is create a symlink which overwrites the normal position that the help files would be, resulting in a strange error when uninstalling and resulting in 4Pane being unable to find its help files.
I will probably have to overwrite doinst.sh with something more sensible. Should be able to look at it in the next few days, I hope.
Paul.
