If you are running PDF2Word on a low resolution desktop, you may find that the applicaton window doesn't seem to be properly sized, and that sliders or even menu items may be cut off.
(below image shows a resolution of 800x600)

In order to correct the window sizing issue, locate the PDF2Word shortcut by going to C:\ProgramData\Microsoft\Windows\Start Menu\Programs\CogniView, or use the shortcut in your start menu to Open file location.

Right-click on the PDF2Word shortcut and select Properties.

From the Shortcut tab, find the Run option, then choose "Maximized".
Click "OK".

If PDF2Word is open, close it and re-launch it.
PDF2Word should now be maximized to the full screen size.
