Steps to reproduce the problem:
1. install fvwm2 as your window manager (both 2.6.5 and 2.6.7 exhibit the same problem)
2. have a configuration that has "Mouse 1 W CS Move-or-Raise" somewhere (can be just one line)
3. browse to www.freebsd.org
4. try selecting "Developers/SVN Repository"

What is the expected behavior?
This should go to svnweb.freebsd.org (same tab)

What went wrong?
nothing happens. tab doesn't change
