Hi Michael,

> Hi PaQ, this looks like one of those things that gets corrected automatically when the file is read back in, because when I open your file over here it seems to be all ok now.

Something to do with the viewport settings maybe ? Because here I still have the problem if I reopen the file.

No I don't, but I will reproduce the construction here.

I'm not sure if I was clear enough, can you fillet any little holes from the model without any problem ?
