Hi,
The documentation for test.complete can be found on the documentation here. When you want to look up a command for an element, go to its documentation page (in this case, the documentation page for the Html element). Or just use the search field on the top left corner of the website.
What you describe though sounds familiar. There was a bug like that in previous versions of PennController that I thought I had fixed in more recent versions. Which version of PennController are you using?
