I´m @ my day job right now, but will try to help you...Will reply as soon as possible.
Okay..
-The Special font for the Blind is Hybrid Outline and that "Auto applies" for it´s added in the Actual blind, but that´s mainly only used on startmenue & Taskbar-buttons, I´m not sure what font is used for the "Pop-up menues" you´re referring to, but I think it´s called "Plain".
-If Vampothika sees this she might come in and verify that info & some.
-If you have tampered with Text/font settings in any way I would recommend a fresh download of WindowBlinds again cause since you are new to this as you say it would be hard for you to get it back EXACTLY as they were.
Make a "Registry Clean" after Uninstall so no remains of WB-settings or other are left. Restart, download WindowBlinds again & Re-apply The skin(s).
-What Os are you using ? The Skin is only for Win 7.
That´s what I can come up with at the moment.
