When unchecking Attached in the toolbar (an option that is not documented anywhere) I am not able to re-attach. Checking the port using sudo lsof -l -P | grep 9000 shows that the connection to the server remains in the CLOS_WAT state, forever.

Clicking attach in this case will result in the text "Could not open socket" appearing in red somewhere in the statusbar of MacGDBp. The checkbox remains checked though, so the application is in an undefined state.

Please document the Attached checkbox, and check to see if MacGDBp is the closing connections. If MacGDBp can't connect, don't set the checkbox to selected.

Thanks for the report. I think this is fixed with the attached build. Please test it and let me know.

The "attached" checkbox indicates whether or not MacGDBp should listen for new connections from the debugger.

I tried 1.5.0.102 and the "Attached" checkbox doesn't seem to work for me at all. The "Stop" button works correctly now though (didn't in 1.4.1)... (Before the Stop button would completely break everything and I had to re-start the app).
