I had been using Windowblinds 7 for quite some time now and had this same transparency issue at the top of the window where the control buttons are located. Sooooo....I decided to upgrade and purchased Windowblinds 8. The transparency problem was not there initially, all the Blind Themes seemed to be displaying properly with no transparency issues at the top of the window, I was very happy because I got to experience the full beauty of the entire Blind Theme. Then.....I installed a blind theme called " Aero Midnight" then BOOM ! The transparency problem came back and now there is no fixing it, even when changing to a theme that had previously been working just fine ! Am I pissed ? " YES ". I feel like I just wasted money on an upgrade that is still broken. So sad really. I have not heard a difinitive answer in the past regarding this issue. Can it be fixed ?

P.S. - Apparently the problem is only with Google Chrome, I may just have to make Internet Explorer my Default browser again , unfortunately.
