Tecnomatix Graphics Viewer not updating after an undetermined change

Graphic Viewer not showing changes or updating until a click or mouse action on the screen.

Solution

Changed the OpenGL level to a lower setting, and everything started working as before. Options->Performance->OpenGL
Reset to the original OpenGL level; graphics was working OK. Resolved.
