The wireless Bluetooth USB worked because it is 64-bit compatible and the driver is 64-bit. I have noticed on the Internet that whenever I request software or hardware that is VISTA 64-bit compatible, I get many responses. When I go into many of the sites they only use the wording new VISTA compatible - this was the same when I went into BT.com. I specifically searched for VISTA 64-bit compatibility and came up with topics that were not germain. The mouse that I received with my notebook, Dynex, says on the front cover Certified for Windows VISTA, but the manufacturer does not support 64-bit!
My first experience with this issue was in early October of this year when I was searching for bootable software for DOS and Windows, that would repair Operating Systems, etc. I specifically requested 64-bit VISTA in my google search and came up with three or four Companies. The one that looked the best to me was Spotmau PowerSuite 2008, so I bought it, as the site advertised VISTA support. Because of the problems I was having with my notebook, I requested that they send me bootable factory CD's for DOS and Windows.
When I booted my notebook the PowerSuite software came up and I was able to use the mouse to open the programs I wanted to run, but the keyboard did not work. I tried several different keyboards (still have my old IBM's, much better than today's) and they did not work. I sent an e-mail to Spotmau support and their reply was that their software does not support 64-bit Operating Systems, and they refunded my money promptly.
The DOS version works great, however, I used the Windows version on my daughter's Compaq Presario, running Windows XP and the keyboard did not work. I would not recommend their software.
The moral to my story is "let the buyer beware", don't assume anything and remember that there are not that many software or hardware manufacturer's supporting this Operating System and for good reason - it does not play well with their products and they realize that the Customer is their livelyhood. Some of the problems that many of you are experiencing with VISTA 64-bit is due to software/hardware compatibility and driver issues (64-bit), as well as the fact that the system is not ready for market.
When I first spoke to my Customer Case Manager at HP, after many problems, she said to me "did'nt you know that there were problems with the VISTA 64-bit OS when you bought it. I told her that my wife bought the computer and I was confident that Best Buy did not tell her. I asked her why HP and Microsoft were selling products that did not work properly. She told me that they were ironing out the issues, and inferred that most of the problems were with other vendor software. Oddly enough, even with the bad hard drive (that they had to re-image), the programs that worked on my notebook were not Microsoft or HP products. She told me that the feedback they are getting from the Customers will help them to improve the Operating System. Needless to say, I was astonished at her responses.
Sorry again for rambling on.
