Hi. I've now installed Active Site in two separate environemnts (Windows and AIX) in the past few weeks. I have run into the same problem on both. I receive a "Stack overflow at line XXX" from Internet Explorer. Then the site becomes unusable. I was posting a couple of documents to the public website when this happened, if memory serves. Have you seen this before? Regrettable as I was just about to show somebody how (well) it worked. is there something else I can provide to help troubleshhoot?
