Topic: Problem opening SV in IE?

We have set up about eight seperate SV galleries on our website.  I noticed today in checking, that I can open three or four of the galleries but then (I'm guessing) IE stops opening any more. 

I am not trying to open all at once, simply open one, check the images and close the window then go back to the index and open the second.

When I've gone thru a few galleries and try to open the next, the page will not display and eventually time out.

Is there an IE bug fix or something else that could be causing this?  BTW, we have not had any problems with using SV in the past and have had it operational for some time. 

Thanks in advance.
