Shedding some light

 From:  BurrMan
Hi Michael,
I would like to ask you to shed some light for me here... This is a sample curve and solid created from it.... If you select the top face and run a fillet of .04, one corner kindof goes bonkers..

I couldnt find anything that would indicate for me what is happening. Nothing needs to be "fixed" for this... I am really looking for more of an underlying explanation of what happens at this area as it is just a single curve from a larger object that someone is having issues with and I am helping out.... Your explanation may help me track down whats going on in the larger model...
