Will this also work for MOSS 2007?
It is not mentioned, that it will not work for MOSS 2007 or that it even depends on SharePoint at all, but I get the error "Cannot find custom tool 'MaventionMinifiedCssFileGenerator' on this system."
Although I haven't tested it, it should theoretically work. The bug that you are mentioning, is something I have stumbled upon myself at some point. I thought that it had something to do with me installing VS11, but apparantly there is more to it. I'll see if I can find out anything more about it and will let you know if I find anything.
