Apparently the latest version of the browser, IE10, doesn't support the gradient filter (CSS in HTML) once used for displaying the left hand side color boxes.
While it's not that big of an issue, I still felt compelled to sort it out. First I tried using some standard gradient CSS picked up from ColorZilla, but ended up using just static colors. I got the gradient to show OK in the browser, but not in the Ax form. Anyway, I just wanted the colors and not the fancy effects.
The solution is easy. Just change the HTML code put in the ActiveX components. Comment out the fancy gradient stuff and put on your own red and blue. Here is how I did it:
If anyone feels like sharing a different solution, please comment. For all I know, this will be sorted when Internet Explorer 11 is released. :-)
