Do you have multiple montiors? (Support requests)
If you have multiple monitors, the problem should be caused by your layout. If not, then I don't have an idea of why you're not getting it to run.
Please try opening icomancer using the "Reset settings" shortcut. That'll clear any preferences -including the defaults- and put everything on zero.
Please let me know if the solution worked or not.
