Firefox works but not IE

[User (Legacy) 2]

Not sure what the exact problem here is.

I can open the graphs fine in Firefox 2.0.

IE I get "Internet Explorer cannot open the Internet site http://....."

Operation Aborted

The browser then craps out and I have to close it.

If I have the graph wrapped in an UpdatePanel it works, but I can't enable 

viewstate or everything shows....(all the graphs for the tool bars and 

such).

I'm guessing it has something to do with the .Net enhancements for IE?  Not 

sure exactly what they are, and security.  I turned off McAfee antivirus, 

but it didn't help.  I used the url to the png and was able to see it in 

each browser without problems.

Everything seems to work fine locally while developing, but not I put it on 

a UA server and these are the problems.
