Do you want to continue waiting for your application to launch?

I am getting the following message when debugging Web Edition code:

Your application has failed to launch. If you continue to wait, it may launch. Otherwise, see the Messages pane for possible information that might explain the problem.

ReStarted the mac.

I am able to click on a URL in a document and Safari launches ok.

Ideas?

Is the debug port in use? Could there be a breakpoint or something in the App object that is preventing the app from starting?

I changed my default browser to Chrome and back to Safari.

All seems normal again!
