Issue:

After upgrading Windows, clicking the Open command in the ZW3D causes it to freeze, and the file icons are displayed incorrectly.

Causes:

The latest Windows updates have led to errors when using Qt to retrieve file icons.

Solution:

  1. Select Configuration under Utilities in the menu. Or select it from the top-right Corner of ZW3D.

  2. Within the Configuration dialog box, check the option Open file using Windows dialog box in the Files tab.
