I am truly annoyed by n00bs who think Vista is screwing up there Blockland, I reckon its because of handicaps saying XP is better then Vista, True in some cases but Vista is the future if you like it or not, I don't see some of the new better features on Vista on XP. As Blockland pretty much runs exactly the same on Vista as it does on XP there is no problem with Vista just your handicapped computer skills. If you cannot portforward don't blame it on Vista, if Blockland isn't working don't blame it on Vista.
The ONLY problem that I HAD with Vista (Other then the commen problem of Crashes etc like XP) was the UAC (User Account Control) It screws up allot so I simply turned it off then my Vista problems where fixed. The only really type of difference for me was the theme and layout change, but I got used to it.
