We're currently looking into this. As a workaround, reset the docking layout to default by deleting the following registry sections:

HKEY_CURRENT_USER\Software\Allround Automations\PL/SQL Developer\Docking
HKEY_CURRENT_USER\Software\Allround Automations\PL/SQL Developer\Docking2
HKEY_CURRENT_USER\Software\Allround Automations\PL/SQL Developer\Docking3
