--- Comment #11 from Karl Relton karllinuxtest.relton@ntlworld.com 2009-01-14 15:34:02 --- Yes - still gives the same problem.
I think it will always give this problem, because the application seems to be at fault in expecting a ':' after the base directory name.
The only solution I can see is to provide a (per app) user switch to revert unix shell folder functionality for this app.
