Note: This does not happen on Windows/Delphi or Windows/Lazarus, only Mac-Cocoa/Lazarus
If I resize my mainform "grabbing"
*bottomright* or *bottomleft* of my statusbar which is placed at bottom of form
My main PageControl suddenly changes active tabsheet.
(i.e. to trigger the problem I have to be resizing both height and width at the same time. The problem does not present itself if I grab at the middel of the bottom and only resize height)
By placing a breakpoint at the TPageControl "onchanging" event I can see om the callstack - but not what actually triggers it.

Any ideas on how to see what triggers this odd problem?
