This week, using Creo 8, I've noticed that the toggle Datum Plane function does not seem to work properly. In any instance, whether I'm in an existing part or creating a new one, the datum planes do not show up when I activate the datum plane icon. What I do notice is that when the key is activated, I can mouse scroll over where the datum plane(s) should be and it will highlight the datum plane(s) until the mouse scrolls away. If I activate a function, such as extrude (or others also seem to have the same effect) and then cancel the function before completion, the datum planes will appear. When this happens, the datum planes will now not turn off when pressing the Datum Plane icon. The Datum Axis, Datum Points, etc. seem to work as normal. Up until this week, I have never had any issues and I have not changed any config files, at least not intentionally. Has anyone seen this happen before and how was is mitigated?
