after upgrading 4.2.4b to 4.2.5 the synchronized browsing (Commander GUI) became buggy:
I load a saved session, then I enable synchronized browsing (CTRL+ALT+B). Local and remote there is the same directory (e.g. "fileadmin"). When I change into it from local, I get an error message, that the directory some/path/etc/ does not exist on the remote server, where the displayed path contains the *local* path. When I change into the directory on the remote side, everything works fine. The bug does only occur directly after loading a session (after sucessfully changing directories on the remote side, the error never shows up for that session).
Downgrading solved the problem.
I am using Windows 7.
Another non-related issue is, that the windows installer should demand admin rights (in Win7 there should come a popup that prompts you for the admin password when you are a normal user).
