task scheduler doesn't save task

I have webroot's spysweeper, installed on 3 pcs....and two run xp...scheduler

is fine on those. but on my vista pc....it will not save a scheduled sweep

of the pc. it looks like it saves it..but then when i leave that tab and go

back in the schedule tab, it is gone! i spoke with webroot, and they say it

is a known issue with vista's task scheduler....I verified this by running

the task scheduler directly, and scheduled up some tasks, saved them...then

after clicking OK..the task list refreshes, but my new tasks are not there.

so it seems it is an issue with task scheduler. does anyone know the fix for

this???

Thanks!
