I don't even know if anyone is going to be able to help but here goes.
I have an IP 2007 form and I am hosting it in a windows application. I have a windows tree control on the left hand side, when i click on an item in the tree control it inserts a node into a section of the xml and displays the currently added node in the repeating section i ahve on my form. This was working fine but all of a sudden after i add about 20 items via the tree control the infopath form FREEZES. It will still add items if i click the tree control, the views still switch ect, but the repeating section no longer updates (as in the newly added node no longer appears in the repeating section) but i know the node is added becuase if i save the form and load it again the node is there. Anybody run into this before?
