Objects stuck in Bounds view on Maximum Draw Type

Hi All, I have a problem that I can’t seem to fix.

Every now and then, for no apparent reason, an object will pop into ‘Bounds’ view on the ‘Maximum Draw Type:’ setting. I can go into the Maximum Draw Type and change it back to Textured, but as soon as I select any other object, the first object will pop straight back to Bounds again. The only workaround I have found so far is to duplicate the object, then delete the old one, but this is a real pain if the object is in a linked hierarchy.

Is there any way that I can prevent this from happening, or is there a better fix for it than duplicating and deleting?

Thanks
Wayne
