Thank you for the post.
“The other database that I converted from fp7 to 13 does not display the same behavior.”
This would indicate file corruption and I would recommend running recover on the problem file to see if it might be damaged.
Things to keep in mind about Recover:
While Recover almost always detects and fully corrects any problems with your file...
1. The recovered copy may behave differently even if recover reports "no problems found".
2. Recover does not detect all problems
3. Recover doesn't always fix all problems correctly
4. Best Practice is to never put a recovered copy back into regular use or development. Instead, replace the damaged file with an undamaged back-up copy if this is at all possible. You may have to save a clone of the back up copy and import all data from your recovered copy to get a working copy with the most up to date information possible.
And here's a knowledge base article that you may find useful:
Afterwards, I would recommend testing the recovered copy to see if the behavior persists. If the issue continues, then try rebuilding the layout from scratch (no copy and paste of any layout objects) and testing the newly built layout.
Please keep me updated with any progress.
