Undocked Object Palette window will not dock or pin to the right hand side of Editor window
説明
The Object Palette window was accidentally undocked, i.e. the window is now floating. When dragging the window over to the right side of the Editor Window, the gray outline does not switch to the docked outline, so the window cannot be docked.
原因
Issue only seems to occur in a dual monitor environment
対策
Move the whole Toad window to the other monitor. This will leave the undocked Object Palette floating in the other window. Drag the Object Palette window over to the other monitor and docking should now be possible. When the window can be docked, you will see the gray outline switch to the size of the window you are docking it to.
