No windows visible in AQT

Sometimes, after you have signed onto a database, you will be shown a blank screen without the Database Explorer (or any other) window visible.

What has probably happened is that the windows have been positioned a long way down or to the right so are not in the current display area. AQT saves the position and sizes of the windows between sessions, and sometimes these saved-positions can get unusual values.

This problem can happen if you are running a multi-display system and one of the displays has been removed or location changed.

The resolution to this is to:

• scoll right and/or down to find the missing window. Drag this up and left.
• (a better option). Click on Window > Reposition Windows. This will find all your windows and move them to the top-left location.

If AQT itself is not visible, you can bring it back into view with the following procedure:

• click on the AQT icon in the Windows task-bar
• hit Alt + Space. , then hit m
• use either the mouse, or the navigation arrows, to move the AQT window into view
• hit Esc or click on the window to stop moving AQT

If you are often having the problem with dialog windows being out of sight, you can use Options > Window Behaviour > Center dialog windows.
