Steps to Reproduce Behavior

  1. Create a new Visual Basic 5.0 Standard EXE project.
  2. Add two controls to Form1.
  3. Ensure that none of the controls is currently selected.
  4. Press CTRL+A, or Edit | Select All to select both controls.
  5. Press and hold either the CTRL or SHIFT keys.
  6. Click and hold down the left-mouse button.
  7. Release the CTRL or SHIFT key or release the left-mouse button.
  8. Move the mouse and note the shadow of the controls.
