Unchecking ‘Use default location’ should not clear the ‘Location’ entry box - it should leave the default path selected so that it can be easily edited if it’s nearly right.
Of course, if it is not close, a single keystroke will clear it.
(The dialogue chosed for the ‘Browse’ button is a very cumbersome one - the one more like a File Open dialogue is far easier to use).
A ‘Copy Project’ dialogue appears with ‘Project name’ (defaults to"'Copy of "), ‘Use default location’ (defaults to checked), and ‘Location’ (defaults to greyed-out)
Unchecking ‘Use default location’ clears the ‘Location’ entry.
Wasn’t aware that was possible!..
Unfortunately, if the Open AT project wizard is designed by us, this project copy/paste capability is entirely managed by Eclipse itself. Maybe should you post an evolution request at eclipse.org…
