Well, you do. You are not stopping to do so. Why are you reading my posts selectively and try to prove I am wrong or stupid or something? I thought IXEG was different. I am deeply disappointed about your communications and I just told you / will tell you that I will hold my investments until I get the impression that IXEG stands for quality products, for dedication to detail and simulation fidelity and shows some appreciation for customers who ask simple, benign questions. Until today I had no reason to doubt any of this. Apparently this information is important to you: I am capable of running Windows NT 4+Vista+2008+7+8, OSX, Solaris 10+11, Plan9, FreeBSD, Linux. One of them is my preferred platform. But that's totally not the point. (edit: grammar)
