HF10: Can't turn cam off after Log And Transfer

Hi.

I’ve posted this question before on another forum, but not having much luck with any responses, so forgive me, but I’m going to try here.

Canon HF10, MacPro 2.8GHZ (8-Core), FCS2

The problem I have,

I put Canon HF10 select button to Blue Cam symbol on camera
-> I power up the HF10 to mains
-> USB connection to the Mac
-> Canon appears on the desktop as an orange coloured Hard Drive and I get the white Mac Hard Drive symbol as well (does anyone else get 2 x HD symbols on desktop?) I can eject the HD's from the desktop after Log And Transfer.
-> Canon HF10 LCD asks do I want to burn a DVD or have a PC connection,
-> I choose PC
-> HF10 LCD then goes on to say that I can’t alter the current function or disconnect the power while in operation
-> Turn on FCP
-> Set to ProRes 422
-> Log and transfer all of my clips successfully.

Great so far, only now the camera doesn’t respond. I can’t turn it off by the power button. The only way I can turn off the camera is to remove the battery while it’s on or turn the camera of at he wall in which case I still have to remove the battery from the camera.

Does any one else have this problem?

Can anyone see anything wrong with my workflow?

Thanks

Michael
