Pickup bar is counted in the measure numbering

My system:
-Ubuntu 9.04
-MuseScore 0.9.5

When creating a pickup measure with the create score wizard, the pickup measure is still counted in the measure numbering. If you right click the measure, select measure properties, it should be marked irregular, but is not (which means it is counted as a full measure). Though it is easy to mark it irregular on your own, it would be good if this were fixed.
