I have a workstation running WinXP Pro + IE 6.0.29 sp2 and it is having issues that when the close button is hit, there is an orphaned iexplore.exe task left in the Task Manager that takes up about 120 MB of memory. After this is repeated a number of times the orphaned task is taking the majority of the 4GB of memory.
How can I troubleshoot the problem of why it is getting left around. I have an older machine, same specs that when it hits the same site does not have the same effect.
I have verified that there is no spyware or adware running on the machine.......that I can find.

IE 6 orphan process
