yEd 3.8: Very difficult to edit Properties View->URL with typed text

Question

It is very difficult to change the URL under Properties View for an object.

If I click (once) on the URL text field, an "Open" File dialog opens which is not useful when I want to enter text (http://...).

I've found that I can enter the text htrough the Structure View->Properties->Data, but that is a long path just to enter a URL.

I've experience this on MacOSX 10.6.8.
