Vista - Vista Ultimate bugs

I installed my full version of Windows Vista Ulitmate over an existing
version of XP Media Center. I immediately ran update also.

Bug #1 I found an error message when trying to send email in Outlook 2000.
I was unable to send and receive email and the icon had changed and did not
even provide for a means of sending email, just reply and reply all. The
error message was unable to find WAP.dll. I tried reinstalling Outlook and
this is when I lost the icons for send and forward.

Bug #2 In the Media center, I lost my mouse functionality almost
completely. I could not tell where the pointer was and it didn't respond well
to hunting around to try and find a place to click. It worked but only in a
limited way. I was forced to use the arrow menus to move around and had to
launch the task manager to kill the application.

Bug #3 In the Media Center, I lost sound while changing channels. I was
unable to recover it. It worked fine at first--then stopped about the third
station when I typed in the channel number instead of scrolling.

For those of you considering upgrading, I'd think twice. I wish I saved my
money and bought and iMac--at least their software works.
