Windows 7: IE9 64 bit Version Not Working

Hi,
I have been using IE9 64 bit versoin beta since it came out and it has been working great, until today. Now it takes any where from 2-5 minutes to load any page such a youtube, however the 32 bit version works fine, along with Google Chrome and Firefox. Any one know why this is happening?

-Thanks

Yesterday I installed IE9 32 (Spanish version) at work, and it works fine. I also installed IE9 64 (Spanish version) at home and it always hangs in two or three minutes if I leave pages like gmail or other web pages opened.

Is it needed any service pack for IE9 74 to work propertly? Any upgrade for flash player or another component?

I have checked microsoft updates for my Windows 7 64 Spanish and it seems there is no needed update to aply.

Have you installed the Adobe Flash for 64 bit? It is a beta, however.

Adobe Labs - Adobe Flash Player 10.1

Yes, I had installed it. And I have also reinstall it for all explorer versions and for ie9 64.

I start IE9 64, two instances of iexplorer opens in "task administrator, I open my gmail, I see FlashUtil64_10_2_161_ActiveX.exe is also opened. I open another tab for hotmail, another instance of iexplorer appears on task manager. And after writing and email, I tries to send it, but it does not work, I then try to change to gmail tab and ther explorer gets white with a "no responde" (in english "no respons", I have an spanish version of windows and ie9) One of the iexplorer instances in task administrator shows 50 % of CPU (one of the CPU of my Athlon II X2 250 is 100%, the other is normal) for several minutes until I end iexplorer process through task administrator.

Other times, ie9 seems to be hang, when I click refresh (F5), it shows a dialog "google.com no reponde" (google.com does not responds), I click on cancel, then reloads the page and continues working.

In fact, I am writing this using firefox because I do not trust it ie9 too much, so I do not want to lose all I have write.

Thanks in advance.

The second time I tried to install IE 9 beta I got prompted that I needed to apply some updates first, and got linked to this page.
Prerequisites for installing Internet Explorer 9 Beta
I downloaded the four that applied to me and installed them one at a time. One of them reported it was already installed. I don't know why they got flagged the second time around. My best guess is the IE 9 beta installer tries to download and install them and mine got interrupted for some reason during the download.

NGNL, see this article You experiences slow performance in Internet Explorer 9 Beta

I had all updates applied to may pc, I have tried to apply them again and all says they are already applied. The Only one I have not updated is "Actualización de Windows 7 y Windows Server 2008 R2 (KB2259539 )" X64 SP1 Beta.

My PC seems to support hardware acceleration because the "Use software rendering instead of GPU rendering" is not selected.

Thanks in advance.

I gets and error saying something like "gmail.com does not respond" very often, and then I click on cancel and then ie9 reload the page and continues working ... but this is a little bit annoying


Thanks in advance.

I don't know what to tell you, right now I can't run the 32 version of IE 9, it crashes every time I try to load it. I've un-installed it.

Finally I have uninstalled IE9, it seems that it does not work with Windows 7 RTM versions until SP1
