On low resolution displays (e.g. 1024x768), the plug-in configuration dialogue boxes don't fit on the screen, and, lacking a scroll bar, you can't easily accept the settings, as you can't get to the 'OK' button.
You can tab to the OK button, waiting for it to scroll round to the first setting, and then shift-tabbing back twice to get to the 'OK' button. But on some larger config dialogue boxes, some of the settings are unavailable.
Am I missing something, or should I put this in as a feature request?
