When you right-click the tray icon and choose open, does the main taskbar indicate a window has opened in response to that?
If a window is opening but you can't see it, it's possible it is off-screen for some reason:
- Hover over the main taskbar icon (not the tray icon), then right-click the thumbnail that appears.
- (If the taskbar is set to show individual windows instead of applications, right-click the button for the window instead of the previous step.)
- Choose "Move" from the right-click menu
- Tap one of the arrow keys on the keyboard
- Move the mouse. The window should snap to where your mouse is and become visible.
If no window is opening at all:
- Please make some manually generated process dumps and send them to us.
We should be able to use those to work out where things are hung.
If it is hung, it's most likely due to a third party shell extension or something similar which has been injected into our process, which we should be able to see from the dumps.
