Need Help With Basic BB Code Problem

[ZomgStuff]

Well every time click on a button in my editor, the open tag and the close tags are printed (duh). But the cursor is at the end of the end tag. How can I get the cursor to be in between the open and close tag to make it easier?

Thanks!

This is default vBulletin functionality, it's maybe a cause of your style (if you have one other than the vBulletin default). You could maybe contact the author of that style.

These are custom BB codes FYI if that makes a difference
