I also have this problem, not all the time, but a couple of times since the update................AND as ever, windowblinds not drawing themselves correctly, ie some of taskbar dissapears, top frame dissapears. This is happening a lot, every day now.
Ive been using Windowblinds now for almost 10 years now, and for the past 5-ish, this happens. I build computers, have numeous operating systems / configurations..... and it still happens.
I really thought Windowblinds 7 would had put this to bed...
