ISBoxer Logging Toons into WoW

Hi All,
so this seems a relatively simple question. When I use ISBoxer to start my WoW clients it seems to launch each window with specific character settings (for examply the repeater regions). Has anyone got a good way to remember which client is each toon? It would seem that the sub account (using battlenet login as the main) should reflect the toon I am logging into, but it seems this is not always the case?
Anyone got any ideas on how to determine what toon logs into each client window? Are the windows opened in order of their slots?
Thanks for any insight

yes windows are ordered by the slots you set up in the Character set. This governs which window is which toon.

so then if I have a messed up log in where the sub accounts are wrong would the only way to identify which toons are which be to restart all the clients?
Thanks :)

I have a mapped key that for each toon shows a popup with the character and account name.

That's a good idea, Firmpete.

I've always put the toon from Account A into Slot 1.
And Account B into Slot 2, etc.

Slot 1 opens, then Slot 2 etc.

The repeater regions are tied to the character set.
So when you launch the set with whatever team, the toons are in the same slots as they were when you set repeater options.
