CAM Pro - Manufacturing Gateway "OK" Button Becomes Unresponsive After Changing Units

Creating a new manufacturing file for a model in the Gateway application. While selecting a manufacturing template, if the units are changed to something different from the actual model's units, the OK button becomes unresponsive and does not proceed further.

Are you seeing this warning dialog

If not, the user has picked the "Don't display this message again" option before closing the dialog sometime in the past.  That can leave the software hanging waiting for a response.

Get into SECaMPro in some existing file.  Go to Menu; Preferences; User Interface

On that dialog go to Options and click the "Reset don't display this message again" button:

Now go and try to create a mixed units mfg setup.
