Problem with action button written in lotus script

Hi all,

I have an old lotus application. It was designed in lotus 6.5.

I use Lotus Designer 8.5 to modify it. I have a problem with a form in it. This form has some action buttons written in lotus script. When I run the application, the browser still shows the action buttons in this form. But when I modify it (such as changing its background color), the browser does not show the action buttons.

I search the Internet and find that the browser does not show the action buttons written in lotus script. But I do not know why the action buttons still show on the browser when I run it the first time (without any modifications).

So, what can I do to modify this form and its action buttons still show on the browser?

I greatly appreciate your help.

Thank you very much!
