IE hangs often: "Problem Event Name: AppHangB1"

IE hangs often when I click or right-click a link and forces closure of all
open IE windows. In the dialog that asks me to close I found: "Problem Event
Name: AppHangB1."

Any way to fix the problem?

Thank you for your help.

More information about the crash:

Thanks.

Most right-click problems are caused by third-party programs that put an
entry into the right-click context menu. The free ShellExView is an
excellent tool to ferret these out:

Right-click is slow or weird behavior caused by context menu handlers -

Thank you for your answer.
Any idea about the problem with just a click on a link? It still happens.
Thanks,

Try running IE in "no add-ons" mode. If that doesn't help and the issue is
only with IE, post in the IE newsgroup for help from IE experts (of which I
am not one).

MS webpage explaining add-ons: http://tinyurl.com/2tro8f

Right-click on the blue IE desktop icon and select Start without Add-ons; or

Start > (All) Programs > Accessories > System Tools > Internet Explorer (No
add-ons).
