This is not a issue with IE per say, it is poorly written software that runs on top of IE. Blaming IE is like blaming a Kubota for having a flat tire from a nail.
That said, I use Chrome for certain web sites that have not updated there code to operate properly with the current version of IE, but my default is the latest version of IE (version 11 for win7) and it gives me the option to stop long running scripts. This is a issue on many web sites, not just this one.
I know people think Windows and IE is the cause for all things wrong, and it is certainly not perfect as is anything built by man, but if you had a good running Kubota, bought a new set of tires and then the tractor got stuck, would you blame the Kubota or the tires? Same with OS, I have had certain windows OS's run as long as almost 2-1/2 years, without one shut down, but as soon as I added a third party software package to it, nothing but trouble, so is it really the OS, or the third party software to blame?
