I thought I was the only guy that had a "Not Responding " problem with Pro/E Wildfire 3.0. Another person where I work now has that problem since changing to Wildfire 3.0. I tried updating the graphics driver and changing the graphics environment from opengl to win32_gdi but the problem never went away. I tried PTC Tech. support but they were of no help. Is there anybody out there that has the same problem?
