### See ´How to get an initial tree´
## When I'm using the Phylip tools for building trees, I cannot access the Phylip menu.
### There is a second menu-button in the tree-build sub-menu which starts the original phylip programs with interactive access to all parameters.
## It would be nice to be able to close a database without having to exit ARB
### Use 'File/Quit + load other database'
