UE 1.61 stuffit bug or not?

[Billabie]

Universal Extractor 1.6.1, W2K and WinXP

I have an old stuffit file (2005 or older). Universal Extractor reports it as a stuffit file, and unpacks it just fine, then it reports failure and deletes the folder. By setting UE to idle priority with Process Explorer I was able to recover all the unpacked files, and they are all good. I can upload the archive if it helps, but it's 515k and I don't have anything that will edit it, so I can't do it now. I didn't find any reference to this, but I wasn't as thorough as I could be. It happens even if the work is done in C:\temp, so it isn't a folder name length or spaces issue. Beyond that I dunno, and I got my files out.

Is it a bug? Is it a known problem?
