Guys,

I have set my preferences for NO Modfit tasks, but I keep getting them.
Yes I already did the update request from BOINCmgr, but your server keeps sending these tasks to me. I have to abort them because they always goto Exit 0 errors.

Does the line below your preferences look like this?
If no work for selected applications is available, accept work from other applications? no
If not, you will get Modified Fit tasks when the others run low.
