You see, this is the thing I'm talking about, you say msstyles are "solid and stable". As someone who is quite familiar with MSSTyles, they have problems too. Lots of problems. Just the ones that come with XP are solid (and many others made out there are solid but plenty of others have serious problems, particularly with the Start bar and properties dialogs.
What is honest is to say that you aren't very familiar with the issues you are talking about and have a double standard in how you judge things. Obviously the more complex something is the more chance for failure there is. But then again, look at Aston shell, it wants to replace the explorer shell and in doing so, the more complex the theme, the more weird things happen.
MSStyles is not more compatible than WindowBlinds. The underlying system in it simply excludes everything that might possibly give it problems. It has problems with Dephi apps so it just doesn't skin them. It has problems skinning menus so it doesn't skin them.
Heck, msstyles won't even skin programs that aren't explicitly theme aware. Try running Adobe Acrobat. Not exactly an obscure app and it mostly looks like Windows 95. Then run it with WindowBlinds and it's fully skinned.
WindowBlinds isn't just msstyles with console skinning and menu skinning. It has hundreds of features and capabilities that msstyles don't have. But you don't seem to be interested in that because you want to stick with your agenda. Heck, by your definition, Aston is "buggy". Lots of people are having problems with it. One visit to your support forum verifies this. But there is a difference between a program being buggy and not being compatible on someone's skin.
Your entire argument boils down to this: With WindowBlinds if you turn on all the features and load up a third party skin that installs a set of fonts that don't support Crylic then it will have problems on the Russian version of Windows and with an obscure shareware program you have.
And from that you decided to call WindowBlinds "Buggy". And this from a guy who suggests people dump Explorer for an alternative shell where nearly every theme requires significant tweaking in order to work correctly.
I think you should find somewhere else to peddle your agenda.
