In ver. 4.9.7.8.1, the component - menu does not take too well to retyping the name of each button. The only way I could rename each button has been to type a letter in the text space, click in the text space, type the next letter and so on.
That element seems to have little problems... Workaround (until fixed) is to use "edit items" button to rename a menu item.. (no html caption then I guess..)
I also found another problem with the component - menu. When I add the action open URL and type in the url in the space, it will (the link that was typed in) disappear when I leave that menu and come back.
I just went back to add a button with a url link and the same thing there also.
These problems are now fixed and version 4.9.7.9 will be released tonite.
The OpenURL action was the first of the opensource elements. It has had a few teething problems over the last few weeks and so opensourcing has been on hold until the technique looks more stable.
I've attached the OpenURL action definition to give you guys an idea of how opensourcing works.
