After a bit more testing, it was still not 100% robust, so this fix  
will bring the change in line with what is done on other OSes (Linux)  
and works in all tested cases.

For reference, this was tested with:

osgviewer <file>.wrl                (file in current directory)
osgviewer <dir>\<file>.wrl          (file in child directory, relative)
osgviewer .\<dir>\<file>.wrl        (file in child directory, specify current)
osgviewer <drive>:\<dir>\<file>.wrl (absolute path)

and works with all. Sorry for the noise on this.

J-S
