At the Build Windows conference, we took a few bug reports in person at our expo hall booth. I'm not able to repro one of the bugs and I didn't get contact info for person that showed it to me.
The problem was typing "System:" caused VA to change "System" to "system" in a C++/CLI project.
If you are the person that reported this problem, please respond here, or contact me via forum mail or through the contact page at http://www.wholetomato.com/support/contact.asp so that we can try to nail it down.
Also, you may want to update the directions for log capture to mention Windows 7 (and 8?) and mention VS2010. I had to look around a bit for Startup.log. Mine was in C:\\users\\<userid>\\AppData\\Local\\Microsoft\\VisualStudio\\10.0\\Extensions\\Whole Tomato Software\\Visual Assist X\\10.6.1856.0\\Data
