Check Boxes are Inoperable in Ubuntu Theme

I haven't tried other themes, but it seems that check boxes are inoperable in Ubuntu theme. LightBlue seems fine.

Tested the same, although I'm using the new Clifton Blue theme.

Using Chrome, AwareIM 5.5 (1602)

There is indeed a problem with Ubuntu theme, which we'll fix. The Clifton Blue theme works fine for us.

I was just confirming that I was getting the same issue with Ubuntu but I'm using Clifton Blue anyway which has no such issues.

This should be fixed in build 1606
