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.

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.
