Yes it seems to have something to do with the SDI setting.
I made 2 short films about it.
The initial situation SDI on: The table editor only opens with ctrl+click twice Switch to SDI off: The table editor opens immediatelyBut now it seems to be getting weird....
1. Restoring the initial situation SDI on.
2. Switch SDI off. The windows are not maximized!
3. Maximize a Window results in SDI is switched on automatically
4. Again switching SDI off (same as in point 2)
5. Now open Table Editor by ctrl+click on table name in SQL Window.
Table Editor Window is shown maximized but SDI is still off
6. Close Table Editor. Note the next Window (a Sql Window) is maximized and has resize icons. SDI is still off.
This is a state that I have not been able to reach before. Because maximizing the SQL window always resulted in switching on the SDI.
Here is a short film about it.
