Sorry to necro a thread, but this was the only one that I found that has the same problem is me (so far, still looking).

I wanted to return to multiboxing this year with WoW Classic, and I decided to scrap all my old isboxer setups and start new.

Part of that was setting up all my macros inside ISBOXER.

However, I am experiencing the same thing as the OP of this thread and haven't found a solution. Basically, if I set one of the Quick Setups to a keymap, it works. (in this example, I tested with the /console reloadui macro). However, if I create my own, say, a simple /say hello macro, it doesn't seem to work in game.

I am no means a master at this, so there could be something I am missing. I used to have this working once upon a time. I am using the new Named Macro interface. Every macro has a unique key combination that doesn't conflict, isboxer does successfully export. I added the correct teams and groups (with a goal to create dps rotations for each class type). However, even a simple macro to window self doesn't seem to work.

The Keymap in question is:

WoW Macros Classic -> WoW Macro Simple Pet Attack

Only the 4th macro works (/console reloadui)

I tested all of these other macros in game first and they seem to work if set up in game as a macro.
