Are there any mapped keys which are different for this team, then for the team with the warlock?

There has to be something different...
If this behavior is not observed when playing the warlock.
But does exist when playing the other toon.



Your best bet will be to post your ISBoxer config.
Possibly here, but on www.isboxer.com (in the forums) might be a better place.

Click File, and copy setup to clip board (check the option to hide your account names).
Then go to www.pastebin.com
And paste the profile there.
Have it save for a month.
And then copy the URL, and paste the URL in your post.

That way, people who want to help you can load your set up.
And its often easier to visually check for something, then to notice whatever off of a description of the issue.
