My Evernote auto-updated to the current release (10.70.2) and I noticed a bug.
A table's top border line does not show. If you click on the table you get the table bar to add columns etc, but when you leave the table that bar disappears (as it should) but does not leave a border line.
It worked fine till this release. Doesn't stop using Evernote but just makes the layout look bad.
Hope this helps.
