--- Comment #2 from John Ervin jervin@cfl.rr.com --- In my case, I mount it on /mnt/ddrive as /mnt/ddrive/bk7. This doesn't work. I could point winecfg at /mnt and it will work, but specifying /mnt/DDrive or /mnt/DDrive/BK7 do not work.
This also happens in the current version of Crossover btw.
It's an annoyance and makes it more difficult to run the program on multiple virtual and real machines because you have to make sure that you always specify k:/DDrive/BK7 for every file rather than k: and if you change that slightly between machines, you have to go do a global update to change the file paths.
But it is circumventable by being careful.
Brother's Keeper is a VB6 application, so it might be related to that.
