I've been using FARR with Windows 7 x64(both beta and RC) and have noticed that while for the most part it works just fine, there are certain very rare programs that it can't seem to launch.  The only example that I can provide at the moment (because it's the only one that I use enough to remember) is VirtualBox.  I have no idea why, but when I try to launch the VirtualBox Manager using FARR, either nothing happens (if the "Launch Method" is set to "Method 1 - ShellExecute") or Windows tells me that the path to the .lnk file does not exist (if the "Launch Method" is set to "Method 2 - ShellExcuteEx" [SIC]).  Both the path to the shortcut and the executable exist and the shortcut launches just fine using Explorer.  I can't figure out what is different about this program.  I've tried compatibility modes, security settings, etc.  Seems to be something with the path, but I can't figure it out.  Has anyone else seen anything like this?

I would love to have the ability to set process tamer rules based on the full startup command line, not just the exe (or at least the exe and all flags that follow it).  This would allow rules for specific instances of programs (e.g. svchost.exe).
