Randomly appearing C:\WINNT\TEMP\

The string "C:\WINNT\TEMP" is popping up in unexpected places and I cannot for the life of me find any reference on the web as to why. So far the string is populating fields, along with legitimate data in multi-value fields or as the sole value in single-value fields when they would otherwise be null, and also appearing in emails in place of the DocLink icon; but still behaving as a DocLink. Any chance someone else has seen this behaviour and knows how to resolve it? The only hint I may have is that the fields are being populated using LotusScript and that the emails are generated using LotusScript. Otherwise I am open to questions.
