Tables in view have borders

Suddenly all the tables in html messages in the viewer have dark borders. How do I reset them to zero

This started with the Pandora 4.1.4 update, and I have taken this up with Brana via email feedback, suggesting that he should revert to how it was up to and including v4.1.3

I suspect (but don't really know for sure) that it may be related to the changes in v4.1.4 as described by the following in the release notes:
* Fixed the issue where table cells are not cleared after Delete/Cut.
* When table cell-border color is not specified, or contains/inherits bogus specification - default, run-time value is assigned automatically.
+ When table is selected as HTML object, press Enter to insert new line above the table.
+ When table is selected as HTML object, hold Shift and press Enter to insert new line below the table.
+ When table is selected as HTML object, double-click on it, to edit it.
+ Create new/update selected table: Edit/Insert Table.
* Repaired drag and drop of tables.

I don't know why Brana resists right-click Send to Browser. It solves so many problems.

I just downgraded to v4.1.3.1 until this gets sorted out.

I really must revert to v4.1.3.1 and get rid of these borders.

Where can I find a link to download v4.1.3.1 ?

We can now specify border color/edit tables so no need for common style (one for all). [Version 4.15]

If you need to forward a message with "layout table" and you want to make it visible just double click on it and set the border (and the color).
