See www.empirisoft.com/Support/showthread.php?p=700 (esp the section on added parameters).
But short answer is: To avoid the html running off the right side of the screen, you can add a width parameter to the background field like this:
And the html background will hide some objects on the screen--usually just labels. You can avoid this by setting an explicit height for the html like this:Code:myhtml.htm (w.9)
The latter will set a window for the html that is 90% of the screen width and 20% of its height.Code:myhtml.htm (w.9,h.2)
See attached sample.
