Not SWS bug...shortcut is being sent to focused plugin. Modifier
(in your case ctrl) "helps" it get to REAPER instead.

When I created these actions
(to move focused windows to mouse), my idea was for them to be used in various macros/cycle actions (
where this shortcut problem is usually not a problem)...not really sure how useful they are on their own.
