Lenovo ThinkPad and Slow IE New Window

I just purchased a Lenovo ThinkPad notebook computer (T61). This notebook is supposed to be very fast. However, everytime when I used IE and clicked on a link that tried to open a new brower window, it'd be very slow and it'd take a long time for the new window to be loaded.

Finally I figured out the cause of this problem: It's the two ThinkPad add-ons: ThinkPad Password Manager and CPwmIEBrowserHelper. After I disabled those two add-ons, the problems were solved and it'd be pretty fast to open new IE brower windows.

To do so, go to IE's Tools -> Manage Add-ons -> Enable or Disable Add-ons and then disable "ThinkPad Password Manager" and "CPwmIEBrowserHelper".
