Thanks for your help in troubleshooting this bug. We found the problem and have corrected it. If you redownload the skin it should work properly. If you don't want to redownload it, just open C:\Program Files\SmarterTools\SmarterMail\MRS\App_Themes\Viridian\Javascript\Skin.js and add the following text to the file:
function STF_SetHeight(element, size)
{
if (size < 1)
return;
var elem = document.getElementById(element);
if (elem) elem.style.height = size + "px";
}
function STF_SetWidth(element, size)
{
if (size < 1)
return;
var elem = document.getElementById(element);
if (elem) elem.style.width = size + "px";
}
Save it and reload the page and it should work correctly.
