1. Launch Toad for SQL Server 5.0, connect to a database, open an Editor window. Do not maximize Toad.
2. Enter a SQL statement in the Editor on a single line long enough to cause a horizontal scroll bar to appear and the window to scroll to the far right. Leave the cursor at the end of the line.
3. Click Format SQL. The Editor will look blank. The scroll bar will remain on the far right. The SQL is formatted and is on the far left off screen.
4. There is no text on the far right, so there is no reason to be over there. If you click on the screen, it'll automatically scroll to the left where the text is.
This issue has been reported to the development team for fix in a future release of Toad for SQL Server.
