When opening a window within QuickBooks Desktop(Make Deposits, Invoices, Write Checks, etc.), the window appears at the edge of the visible QuickBooks Desktop window or is not visible at all.
A QuickBooks Desktop window normally opens at the size and location at which it was last opened. The current settings, stored in your company data file, can be damaged just like any other piece of data in the file.
This can cause a window to open partially off screen or, it opens so far off of the viewable screen that you are not aware it is open.
A window can also open off the screen because:
Open the window at its default location and size
Cascade or tile your windows
Reset all of your window positions and sizes
