The first description is exactly the same problem !

The problems starts when using "Bring Forward" and "Send Backward" we 
never had problems when only using "Bring to Front" or "Send To Back" or 
with a limited use of "Bring Forward" and "Send Backward"
After reading  the post from  Michael Stahl the conclusion could be that 
the Z-order at a certain point in the editing process visualy visualy 
been changed bij using "Bring Forward" and "Send Backward" but no longer 
can been "saved".
When reopening the document the object seems to  be in "heaven" or in 
"hell".
After using  "Bring to Front" or "Send To Back" the Z-order can again 
been saved , so i suppose "Send to Front" means "Place in "Heaven" 
without z-ordering ?

I found a document who i attached to the issue. The problem is very easy 
to notice when comparing the  (also attached) image of the document 
before saving with what we see after opening the document


  Fernand, the bug report is sort of long, but does this look like it 
could be a similar issue? What would be *really* helpful is an exact set 
of steps to reproduce the problem, but I know that’s sometimes quite 
difficult to get hold of. :-) Maybe some sort of test matrix of actions 
needs to be put together, though this could get too large to manage 
after a certain number of objects and actions moving the objects 
backwards and forwards occur. Chris
