The keys F5 and F6 have no function in version 1.2. So I reinstalled version 1.1.0.3 and now it works again.
To copy or move a file in version 1.2 I have to use the drag and drop function. Nothing else works.
the most probable explanation is that you are using the old translation dll. Uninstall the old version or install 1.2 in a new folder and it should work
