But we come to an issue, we are not able to solve.
After we did many things, we need to click on a <div>-Tag, which open a (I think it is) Modalbox. (Works fine). In the Modalbox we need to click on a Link <A> <some-html>"Close all primary Tabs".</a>
and this last click is not working.
We have interogated the <A>-Tag.
We have tried several rules (Element ID, Inner HTML, Inner Text, Element Index) but no rule is working. We can also interogate the Link several times without any error-message.
I had a look into the source code and saw, that the Modalbox is not part of the code of the mainwebsite (only the function which open it), and the Modalbox has its own source code (starting with <html>).
