Using an IIS application project.
Finding that HTML is going missing when writing large amounts of text back when substituting for tagcontents. Beyond a certain amount of letters substituted for the template (the amount seems to vary), the template HTML is lost one character for each tagcontent letter added.
This problem occurs on the microsoft download example for webclasses called support - by selecting the top option on the CallsDetail or CustomerDetails forms.
I need to find out what triggers this behaviour and a way of getting round this.
