Re: Internet Explorer ??
Ok, I pulled the page up and gave it a good looking over.
1st - there is an error on the page. Internet explorer is probably reporting this to you at the bottom - line 102, char 17. Invalid argument.
This occurs if you go directly to "http://myhome.prodigy.net/" instead of going to "http://www.prodigy.com" first and getting redirected.
They are using java scripting, so if you have scripting disabled/restricted in your security settings this may cause an issue.
They are using cookies - looks to store css information - so if you have cookies disabled, this may cause issues.
The most likely possiblity, due to your symptom (locks up, takes a long time to come up, -or- will come up quickly if you hit refresh a couple of times <shuffles adds>):
They are 'porting out' to other adds. It's possible that one of these adds is taking a long time to load.
They have code in the page for pop up adds. It may be that you have pop ups dissabled and it is trying to pop up something - then having to time out on it.
They pull the latest news - again, if there is an issue with the news server it would cause a delay in loading. I doubt this is the issue though - it would affect everyone and each time too.
I'm not all that good with webstuff anymore, so I probably missed a bunch of stuff.
Have you tried doing a good deep cleaning of your IE stuff - tossing your cookies and clearing your cache? (I use "CCleaner" for doing that sort of thing... IE will tell you that it did it, but won't really.)
