When a selection is made using other mouse selection button options, the selection made cannot be resized or moved, or rotated.
To reproduce:
1. In Tools > Settings > Interface > Mouse tab set for example:
- Left button -- Move
Left button + CTRL -- Make selection
3. When the mouse cursor is positioned to modify the selection, the arrow symbols are displayed correctly but the action can't be performed.
Similar behaviour when the Crop tool is used.
