Dialog windows do not display in an Autodesk application

A dialog is expected but the program seems to hang.

Solution:

Do the following:

• Move the window to a different monitor. Hold down the WINDOWS and SHIFT keys and then press the left or right arrow keys on the keyboard. This may pop the missing dialog into view. 
• Test the issue with a different Windows user. If the other user account works then Reset the Windows Profile
• Use the keyboard to move the window into view. Try this first on a visible window to see what happens   (This works for Vault dialog boxes):
  
  1. Execute the command to activate the dialog window.
  2. Press Alt+Spacebar on the keyboard.
  3. Press the M key and tap an arrow key.
  4. Move the mouse to bring the window into view.
  5. Click the left mouse button to cancel the operation.
• Change the screen resolution to a different value, smaller or larger. This should bring all dialog windows back into view. Move the dialog window in question centered on the screen (or toward the upper-left) and then exit the program before changing the screen resolution back to what it was.
