I should know better than to put betas on more than one computer at a time but I haven't had many problems with most of the MS betas till now. First of all, on one computer I had a real problem uninstalling beta 2. I was finally able to do it and installed beta 3. On the second computer I had a tremendous problem installing beta 3 since it was complaining that it could not write to the registry. Finally I overcame that problem and beta 3 seemed to work pretty much OK on both computers. Then I was in for a surprise. A couple of days later I tried to browse my local network and it would crash every time. It was useless. This occurred on both computers. One is an AMD64 desktop and the other an older Compaq Intel laptop. Both are running completely up to date XP Pro. The symptoms were exactly the same. The good old "So and so has encountered an unrecoverable problem and will need to shut down. Do you want to send an error report?" As I looked at the data being sent I noticed "iebrowse.dll" from version 7 was where it crashed. Both systems crashed in exactly the same place. I then uninstalled beta 3 and hoped that would fix it but it did not. It finally took a successful system restore on my AMD system and a total recovery from a system image on the laptop to get back to where I could actually browse the local network. This problem affects many things and makes a networked computer pretty much unusable. This is just a warning. You may or may not encounter this problem. It is serious enough and occurred on two totally different computers so I would imagine I won't be alone with this problem. I will not install any more betas on these systems for a long time. I hope this helps. If you are going to try this beta, be sure you have a recent backup that can actually be restored. It may mean the difference between rebuilding from scratch or at least a recent restore. Regards, Bluto
