But if you use a startup file
Eg
MultiCommander.exe -F=MyTabs.ini
It does not work for REG: , I Just confirmed it.
It works if the path have been browsed before.. There is an error when going to a subpath on a virtual device where parent folder is not browsed before.. (and REG: is virtual. )
To bad MikeC did not run beta version, then I would have found this issue before
But it is only an issue with startup.. Normaly you will start at REG: and browse you way down. And that work
