Shooting tethered is fine if I go slow, however if I speed up and shoot quickly, my machine will eventually crash and need a restart (only ever in this situation).
I'm betting that it probably hasn't really crashed though it does appear that way. At random intervals (happens on Windows and Mac) a file that will normally go to the computer in seconds instead takes almost a minute and half. On Mac, the resulting image will open in PhotoDesk just fine but the thumbnail will appear scrambled. Closing the contact sheet and reopening will bring back the scrambled thumbnail. On a Mac when this happens it looks like the computer has locked up. The progress bar quits moving and the machine is pretty much unresponsive. If you just let it sit for almost two minutes, all will be back to normal and you can continue shooting as normal. Very irritating but you shouldn't have to force quit anything or restart. On Windows its more obvious that the computer is still working, but it slows to a crawl and gives an error when the image is finally complete. Subsequent images will process normally. A number of photographers have reported this on various forums. I've experienced it. I can't find any one particular series of events that's guaranteed to trigger it. At first I thought it was fast shooting. But I've had it occur on a single frame. In a session where I shoot 200 frames, I might encounter this event three or four times. If the bad frame is part of a burst, the images after the bad frame will come in as normal but only after the bad frame has crawled very slowly to the computer.
Because this happens on both platforms, I'm guessing its camera hardware or firmware related. Of course you may really be having the computer lock up... something I've never seen with Camera Manger / PhotoDesk (I use both on OS-X 10/3/5 and Windows XP Pro). In which case I have no idea what's going on.
I just completed a shoot today on an XP Pro system that involved maybe 300 tethered frames (rarely shot faster than maybe five frames at one every two seconds). I had only one of these slooooow frame incidents.
