Help with commands

[AGITA]

I don't know if anyone here knows anything about this but, ANY help would be appreciated. I am proficient in most OS's but I'm only having this problem in vista. Please help!

In the cmd line, I want to schedule a application to run interactively without resorting to using the "schtask" ***. And when I say that I want to run an application interactively I mean this

c:\(blah) at (time) /interactive "cmd.exe"

So I can run as svchost instead of cmd.exe
Vista gives me an "OK the task will run but not interactively, if you want to run an interactive task use schtask instead because of security threat."

If anyone knows how to use the "at" cmd or correctly use the "schtask" It would make my year!

Please help!
