I have several users that occasionally run into an issue with InDesign. When they try to use clipping it does not pop out from the drop down menu. See image. Most of the 50 users here have told me this happens to everyone just at random times. This is not based on the image as we have tried several and it can be clipped by another user. Also there is a fix as someone used to know how to fix it, possibly trashing a preference file or something, but they are no longer here. Please help. Thank you in advance.
