If you are selecting to perform an action in QuickBooks when a new dialogue window should appear, but instead the program appears to freeze, the dialogue box may be opening off screen. You can tell the program is not truly frozen if the top bar does not change color and there is no hour glass in place of the pointer.
To resolve this, simply hit ESC a few times in a row. This should clear the dialogue box and bring you back to the previous screen. Once cleared, follow these steps to reset the dialogue boxes in your company file:
Go to Window menu -> Close all
Once the windows are closed, press CTRL + SHIFT + C
Immediately exit out of the company file.
Log back into your company file.
All window settings should be at default size, in the center of the first monitor.
