This is one peculiar issue I face. If I click on any other window while the SQL Developer loads up, the initial Sign In window will move to the background and the main window is moved to the foreground. Since the Sign In window is modal, and hidden behind the Main Window, there is no way to interact with the main window. The only option is to kill the SQL Developer. But all subsequent starts will have the Sign In window hidden. Starting a second instance of SQL Developer and killing the previous SQL Developer instance is the only remedy I could find so far.
Steps to re-create:
- Start SQL Developer
- Before SQL Developer loads up click on some other window.
- When SQL Developer Loads there is no Sign In window, but the main window is shown. But you cannot interact with it as the hidden modal window is preventing interactions with it.
Environment: MS Windows 7 Professional SP 1
SQL Developer version: 17.3.1
Setup: Dual Monitor
Come to think of it, the initial Sign In window seems to be useless as you can always initiate connection through the main window.
