Describe the bug

On Windows, it is impossible to create a config file with g.gui.rlisetup (create configuration file for r.li.modules) : I can't set the file name in the dialog

To Reproduce

run g.gui.rlisetup

Try to type something in "Name for new configuration file" : it does not work. And 'Next' button stay disabled.

We should be able to set the filename and click on next to create the configuration file. It works on Linux , but not on Windows.
