Black text in dark theme
I've just bought Windowblinds and Start8 and installed them in Windows 8.1. I've installed the 7Dusk theme that came with WB. I like it, but I have one issue - in some places black text is being used on a dark background, as in the example below (below the white box, where you have to select to agree to the license). I can't find where I can change this; I've looked in the WB configuration, but I can't anywhere that text is set to black. Could someone please tell me where I can change this?
