When I try to execute a seperate dopus session as a different user (e.g. non-admin account for testing NTFS/share permissions), it does not create a new process under that non-admin account even though I have successfully entered my username and password information in. Any thoughts on why this might be and if there is a way to make it work other than having to switch my Win 7 session to that account?
Make sure you exit Opus fully, else the existing instance will probably just open a new window.
Use the exit option on the taskbar jumplist or in the File menu to exit Opus. You should no longer see dopus.exe in Task Manager.
