One thing to note, when the auto-installer installs it forces selection of the winamp path. If a user (for some reason) has multiple copies of winamp, it would be nice if we could over-ride the selected winamp path?
Also for some reason, although I can run R4 standalone, I cannot seem to get the plugin working with winamp 5 . (Windows XP Athlon 2400, 1Gig ram, Winamp 5.02, ATI Radeon PRO 9600)
