IE in Mac

[forddude]

When I try to open a second window in Internet Explorer, the program just quits. Sometimes I get a message that says unexpectedly quit, type 11 error, restart the computer and try again.

What is happening?

Could you please post back some system specs, like CPU speed, amount of RAM, etc.
It sounds like Internet explorer needs more memory.
To do this find the internet explorer program (HD > Applications > Internet Explorer)
Click once on the internet explorer icon, then click on the file toolbar, move the mouse over Get Info, then click on memory.
From there you can change the amount of memory it is using.
But make sure before you change it that you have closed internet explorer. You will need to change the preferred size first then the minimum.
Hope that it helps.
Yuri.
