The menu File/Preferences misses the "..." (ellipsis).
Normally if a dialog box comes up on selecting a menu in Windows the text must have the "..." at the end (see also Import..., Export... or Enter license key...)
Nice feedback, @ChartFreak.
By the same token, each of the items on the File > New Item submenu should include an ellipsis, as well.
Those should be fixed in the next beta build. Thanks again, @ChartFreak.
