That's a feature not a bug!  The idea is that once you
set the sitepath, you don't have to do it again (i.e., it
will be sticky).  We'll probably change the default behavior
in the future since in this case, you don't have the
User Preferences dialog to undo it.

All preferences are stores in <userhome>/.metapps so blowing
away the executable directory won't help.

The sitepath is stored in the main.xml file in the
user's path (usually <userhome>/.metapps/DefaultIdv,
but can be overridded with the -userpath command line
option or by using a different IDV subclass or by specifying
a property in idv.properties).

Normally, you can open the User Preferences dialog and
remove the sitepath from the list, but in this configuration
you don't have that.  In this case, just run:

runIDV -sitepath ""

to clear out the sitepath argument.
