[macos] changed cursor lost when application is re-activated

    XMLWordPrintable

    Details

      Description

      FULL PRODUCT VERSION :
      1.8.161, also seen with 1.9.0.4.0.11

      ADDITIONAL OS VERSION INFORMATION :
      Mac OS 10.12, also seen in earlier versions

      A DESCRIPTION OF THE PROBLEM :
      When the cursor has been changed to something other than the pointer, and the current application is changed using CMD+Tab, and then the current application is changed back again with CMD+Tab, all without moving the mouse, then the cursor stays the pointer.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      1 run attached code
      2 click in one of the cursor boxes to change the cursor to 'hand' or 'text'
      3 move the cursor outside the cursor select box, cursor changes appearance
      4 without moving the mouse, press CMD+Tab to leave the application, cursor changes to pointer
      5 without moving the mouse, press CMD+Tab again to return to the test application, cursor stays pointer


      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Cursor should change back to the 'hand' or 'text' cursor
      ACTUAL -
      cursor stays pointer

      REPRODUCIBILITY :
      This bug can be reproduced always.
