Quote - my guess is that this is one of those IE and the Windows interface are basically the same app kind of things.  when i've had issues like this in the past, i've had to change my IE settings. 

That might be possible. I have never changed anything in IE8, because I do not use it.

EDIT: For those having troubles with extensions in upper case letters, use the ren command in this folder.

Example: ren *.CR2 *.cr2

EDIT 2: I have mixed emotions about my purchase. I like the new GUI and the IDL feature. I do not like much of the content. A new horse would have been great, or some hires outdoor scenarios (like stonemasons stuff). But hey, now I've got an Aircraft Starter and a Concrete Hopper!

As a former P6 user, I like that I can use my SpaceNavigator.
