Excel Add-In Pane Weird Display Issue

[Whit Miller]

I just installed MySQL for Excel with Excel 2013 and it works well except that the UI is very hard to read. The window/pane that Excel provides to interact with the MySQL for Excel Add-In doesn't render well at all on my computer.

As illustrated in this screenshot: http://s10.postimg.org/glnmav22x/My_SQL_for_Excel_weirdness.png

(1) There is empty space on the right side of the pane
(2) I would normally grab the vertical divider bar on the left edge of the pane and drag it left to make it bigger. This does not work.
(3) The content in the pane is hard to read because of (1) and (2)

Apologies if this is caused by my own ignorance of Excel 2013 and unrelated to MySQL for Excel. Any help appreciated.
