Sheets losing references

[mhirsch]

I've noticed a problem where occasionally when saving a sheet the references will be replaced by the values. For example, let's say I create a new 100x100 image in A1, then open an existing 10x10 image in A2, and use Image_insert_item to insert A2 into A1 in A3. If I set A3.place.left to A1.width / 2, sometimes when I save an re-open the worksheet, the value of A3.place.left will be A1.width / 2 and sometimes it will be 50.

I can't yet pinpoint under what circumstances the reference is lost, and not all references in the worksheet will be lost. I haven't kept careful track but my impression is that it's more likely for references in sub-rows rather than main rows. E.g. If I set A2 to C2, that seems more "sticky" than if I set A3.place.left to C2.

Thanks!
