Default drive on start up

I get the last folder used on start up. in the configuration that item is not selected. I would like to go to C:\ on start up and I am unable to find that setting.

I have Opus Directory Opus Pro 11.12 Build 5532 x64
OS 6.3 (B:9600 P:2 T:1) SP 0.0
and windows 8.1

thanks for your help

The Startup Folders FAQ should have all that you need.

thank you - it seems a little round about but I think I have it now
Thanks
