How do I unlock entry dialog to be able to graphically select location with "Locate Station via Datapoint"

Question

This is probably simple, but when using the "Locate Station via Datapoint" command in SS3 dynamic cross section view, I can only key in the location, not graphically select.

Hi Katie, 
 
In troubleshooting this issue, one thing I have found is that if you select the Locate Station via Datapoint command, key-in a station and then enter, the Locate Station via Datapoint dialog box will be checked, locking that station. In moving your cursor, the starting point is locked to the keyed-in station on your alignment. Uncheck Station in the Locate Station via Datapoint dialog box, and you can then select the location by datapoint. 
 
Thanks,
