Inserted Elements Disappear

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Have an existing Pencil doc with half dozen pages with linked images.
2. Added new page. Pasted in grouped elements from a page in another Pencil doc.
3. Looked at previous pages they are now blank.

What is the expected output? What do you see instead?
That unedited pages would appear the same as no changes were made to them or at 
the very least there would be a unfilled box warning that images have broken 
links

What version of the product are you using? On what operating system?
Had 1.3.2 and updated to 1.3.3.  Using it on Windows 7 64 bit.

Please provide any additional information below.
It appears that this process is erasing all or some of the formatting 
information on these pages as it is not just removing linked images, it is 
removing text and shape elements.

Update: This also occurred when duplicating pages in the same document and 
changing properties.

Upon further research into this it appears it was a matter of select all and 
deleting in one page, selected all none locked elements in the entire project 
and deleted them.  A completely different issue entirely
