No one else has problems with broken image links on drop-down menus (all broken) or on the modules themselves (many of them broken, though not all)?

Last night I tried the release candidate version.  Tonight I'm trying the 4.03 version, with the same results.

Before I log in, the UI looks fine.  After I log in, there are broken image links ahoy.  Take the "Links" panel on the default page--that image cannot be found.  It's supposed to be located at:

   http://localhost:1034/mysite/Images/action.gif

Now, an image does exist there by that name, but the folder in real life is a lower-case "images", not "Images", as the link is pointed at.

Could this be the problem?  The casing of that directory name?  I've done nothing to this site; it's out-of-the-box.  How could this really be the problem (the casing of the dir name) and not be a problem that everyone else in the world would have?

Other images appear--let's take the blue pencil icon, for example.  It appears just fine, and is pathed as:

   http://localhost:1034/mysite/images/edit.gif

Again, could this be the casing of that folder name?  The big problem with that theory is that the DNN site is not bursting with posts about this.  Is it an understood problem that I just didn't find the link about?  (I did search the forums, albeit briefly, before posting this).

Thanks for any help.
