This is the Meta issue to track all compatibility issues what came up with the more flexible border design with LibreOffice 3.4. All Bug reports concerning broken paragraph, table or other border viewing in documents created with older OOo / LibreOffice Versions should be listed here. Additionally problems with documents created with LibreOffiec 3.4 with border VIEWING problems in older versions and other general border compatibility issues should be added. If you find a related bug please add the Bug ID as dependent Bug here to the Meta Bug in field "Depends on" and cite the subject line of that bug.
Add "Bug 44708 - FILEOPEN old document: Paragraph border FORMATTING lost"
ooh, neat: there's a meta issue for these :)
+ Bug 39415 - Table borders in word 200x .doc are shown incorrect in writer
I would propose to close this meta bug report because it was not used for a long time and all the bugs mentioned in "Depends On" are already marked as Resolved in the meantime.
+1 for Andy's suggestion. This has seen no use for a really long time. Closing.
