Conflict with User Switching plugin

Hi,

The user switching is not working, with Domain Mapping plugin activated. Before your DM plugin, I was using WordPress MU Domain Mapping plugin without any errors.

I just switched to use your domain mapping solution, but it is in conflict with User Switching plugin, so switching is not working.

The User Switching plugin's author has "no time" to take a look at this issue, so I want you to take a look at it.

Thank you!
