Problem with a visual effect

Hi everyone,

I've installed win7 RC1 on my computer and had a problem that forced me to format my hard drive and install win7 again.

Before I've formatted my HD, when I was standing with the cursor on a window in the task bar, before I was pressing the mouse left button, I could see the widow, and when I moved the cursor away, the orignal window that I was in appeared again. (I could preview the window before I entered it).

Now, after I reinstalled win7, I suddenly can't do it.
And even further, my comp. rate suddenly became 3.2 (and not 3.6 as it was before I reinstalled it.) - but this can also happen due to 2 drivers I didn't find yet.

Can someone help me please and tell me how can I get this visual effect working again please? It's really helps me with my daily work on my computer.

Hope you understood what I was talking about...

Thanx a lot!
sza.

Thanx for the comment,
But it was already set for the best appearance, and it's not working...

Hello Shawn, Thank you for replying!

The drivers that wasn't installed properly and need to be updated are:

1) Azurewave Wireless LAN Driver
2) Marvell LAN Driver

My graphic card ( nVIDIA GeForce 8200M G ) has the latest driver.

And I chose a Aero Theme as you asked me in your post.
Still, it's not working...

btw, I forgot to say that the version of win7 that is installed now is ultimate RTM.

Do you have any idea why it's not working?

Thank you for trying helping me! :)

bummer

try rating your system again. Sometimes, even though you have a rating, windows needs it rated again
