Something I've never seen before is happening on a relatively new installation of IDEA UE 10: When I use TabSwitch to switch to another tab and that tab is in a different split/pane from the currently focused tab, instead of the focus moving to the pane in which that tab is open, a new tab is opened for that file in the current pane.
Can this be turned off somehow? I don't see a Settings section for TabSwitch.
