Yet another question. If you normally would reconfigure LyX, you get a message like "Running configure..." in the status bar. Then you know you have to wait.
What do you expect on Mac if you don't have any window open ? Now, there is no way of telling that configure is running, right ? Do you expect some sort of message popping up ? Do you expect a message box on your screen (as you probably don't want to do any work as you don't even have a view open). Do you expect a sheet to slide down from your menu bar ? Vincent
