I'm running Windows 7 Ultimate with IE8 64bit. There seem to be two versions of IE8 on the machine. One in "Program Files" and another in "Program Files (x86)". The version that seems to be the default is from the "(x86)" folder. However although the (presumeably) 64bit version does the job properly, I have noticed that the (x86) version doesn't seem to close properly and on task manager that although IE seems to have closed down completely, Task manager implies that there are still a number of IE tasks extant (*32 version). Seems to occur when trying to access a link from one page to another for (perhaps) a file transfer which seems to fail in some way. I can find no extra information as to what has happened, and conversely should I make the 64bit version the default in some way?
