Columns keep moving

[Holmes245]

Is there a way to keep columns from moving? It happens all the time. I'll open up MLO and occasionally (more than I would like), the Urgency or Importance column shifts to the left past two columns I've moved. I've moved my columns around in the positions I like to view them. For instance, I've moved my Start and Due date columns to the far left because like seeing the dates immediately before the task names. However, like I said, some columns shift like the ones I mentioned previously. Anyone else have this happen to them? Is there a "Column Lock" feature that I'm not seeing?
