Hello, While you are on the topic of 4.5.1, can anyone tell me if it is compatible with XP Pro Service Pack 2 ? I've been really happy with 4.5.1 (very stable) and have been using it for quite a while. Problem is, my operating system is XP Pro SP1 and I would like to upgrade to SP2 but am afraid of the consequences with Xpress Pro 4.5.1 The release
