Tethering Issue with Aperture 2 and Olympus Evolt E-500 camera

Hello,

I'm curious if anyone else is experiencing a similar problem, because I haven't found anything about it here nor anything pertinent on google. I'm having a problem when trying to tether with the above mentioned camera in Aperture 2. When I connect my camera and start a new tethering session my camera is only recognized in Aperture-2 (E-500) when I have it in 'storage' mode (not 'control' mode). However, when I invoke the HUD windows the 'capture' button is not working (cannot press capture at all).

Any info would be greatly appreciated --- thanks in advance.
