Subject: Questions

Does this problem happen when you launch Designer on Vista and do nothing while in Designer? If not can you give me some examples of the kinds of activities that lend to the problem you are seeing? I would like to see if I can re-create the types of actions to see if I get similar results

Subject: Sorry, problem only with xpage.

Open xpage and work with properties section. Change components names. In iteration write javascript code, etc.
