after creating a series of grid lines. when i try to select any one of them, it automatically shifts the grid line up several feet (in the plan view) and shifts it over to make it an even distance from the next gridline. therefore it is no longer in the correct position (or aligned with the rest of the grid lines). is there a snap setting or something i am missing when i just want to select a grid line without moving it? even with snaps off, it still happens.
i just discovered this is only occuring when working on my external monitor (connected via hdmi). it does not happen while working on my laptop screen. if anyone external display set-up or configuration suggestions, i would appreciate it.
