Right, sorry I misunderstood. I also do not use Auto 3 sec strobing, when PVPing. Ok, well, I had the exact same problem as you are then. I tried to add a toon to an already created profile. I know I goofed something up.

I highly suggest, doing a fresh profile, via the wizard. Sometimes, the wizard doesnt work properly when you havent logged each toon first, then close WoW. Then run Wizard. Select the WoW account, enter your email account name, select your group, then choose the suggested options, but include the one about auto following after combat or whatever it is. (Im at work right now, so I cant see a screen shot of it).

Then save all, and export to Innerspace.

(you can start your windowed instances in any way, but I do it by creating a shortcut from the ISBoxer menu, and then just double click it.

Once everything is up, enter game each toon at a time, and double check the ADDons checkboxes.

Reset all your keybindings to WoW default.

Open Jamba, and reset it all to default too. Double check the initial profile window in jamba so that you see all your toons names, and ENSURE they are spelled correctly. You may also want to ensure that the window swaping is checked, but NOT the window swapping and promote to new leader.

Then set your Jamba follow options as you see fit.

What should happen is... when you SHIFT+CTRL+ALT+ I, you should auto invite all group members.
( ) Check
ensure your Keymap repeater is on.
( ) Check
Ensure the mouse and full repeater is off.
( ) Check

Press ALT+F once, so that your slaves are now following your leader. you can wiggle around to ensure.

Then when your leader targets a mob, he is the only one targeting him. BUT when you begin attacking, the assist me feature takes over and your slaves will target and attack also.

I highly recommend you set up your IWT keystroke after you get this all working properly.

After setting up the hotkey in the game (really, please do that first to avoid confusion), you will need to tell ISBoxer what key combination that is, and set up a hotkey in ISBoxer itself, to perform the broadcast:
  1. In the top pane in ISBoxer, select General under Key Maps
  2. In the bottom left pane, click on Interact with Target
  3. In the bottom right pane, at the top, is a Hotkey option. Click the < to pick a Hotkey. It can be the same key combo you selected in the game, but I personally use Alt+J instead of just J. This allows me to type using the J without having to turn the Key Map off first
  4. Expand Interact with Target in the left pane by clicking the +
  5. Click on Step 1 under Interact with Target (the 1 underneath Steps)
  6. The bottom Action in the right pane is supposed to send the Interact with Target hotkey configured in the game, to all windows. Right click on the bottom action that's there, and select Delete
  7. Right click on Actions and, under Keystroke Actions, select New Keystroke Action
  8. Set Target to Window:All w/ Current (as opposed to All w/o Current, which would never include the current window)
  9. Set Key Combination to the key configured in the game for Interact with Target
After you Export again and ISBoxer reloads the configuration in the game, your new IWT key should work. Target an NPC and press the new hotkey, and your characters should all interact with it.
