From looking at your ISBoxer configuration the only issue with it is that you have the DPS 1 Mapped Key set to Execute a Step when the Hotkey is pressed OR released. With such a 3-step Mapped Key then the activation will be: 1st Press (Step 1), 1st Release (Step 2), 2nd Press (Step 3), 2nd Release (Step 1), 3rd Press (Step 2), 3rd Release (Step 3). That may or may not be what you were intending.

The issue you describe sounds more like a problem with your actual macros. For example, the behaviour you describe is what I would expect from a stuck macro that also had reset=target. I'd suggest posting the macros you are using.
