IMTrick:
As far as "debugging mode" goes I would advise you to contact Lax, as I cannot answer that myself.
Otherwise it would be helpful if you could provide a bit more information regarding your issue and I can try to help you out.

Are you talking about the "Mouse1 Healing Key" that you are using on "Left Click" with your Click Bar? If so, make sure that this key has "pressed OR released" checked so that it triggers Step 1 on Mouse"down" and Step 2 on Mouse"up".
Also something I sometimes do for "manual debugging" when something seems to be wrong is to insert a Pop-Up text message in my keys to see if they fire off at all, or if a certain step fires off as it should etc.
