Microsoft can't code properly. I've noticed this because even one thing in the MSStyles is change, likely you're going to have bugs. DWM is a huge joke. It looks ok as long as every last property is never changed. And in 7 it's gotten worse. DWM flickers in the programslist of the startmenu. Most of the time it won't render anything. The taskbar as I found out apparently can't use sizing margins appropriately and somehow, for whatever reason, affects contentmargins. Great job MS and following though with that "if it looks ok one very particular way, then we can leave it broken." I can understand why Stardock pretty much overrides everything in WB because it's a fucking joke how screwed up crap is. Enough with the rant, on to the details.
In TaskBand2 Part 5, don't set the sizing margins of the left and right values (first two) to anything higher than 13. Here's a video showing what happens if you do.
