Hi,
For those who haven't figured it out yet, you can use your own shellstyle.dll by replacing it with the one in "C:\Users\<USER>\AppData\Local\Temp\Shell\NormalColor" (where <USER> is replaced with your screen name). To see the changes, you will have to "Stop" VSB and press "Test" or simply exit VSB and run it again. You will notice your custom shellstyle being used in conjunction with your VSB application.
Hope this helps someone out there
%temp%\Shell\NormalColor\
Easy for people who just want to copy/paste rather than browse for it if they've never been there.
