Aholtzapfel, I created an account just to say "thank you!".
This was driving me mad; a (rather complex) JavaScript was rendering on my primary (Mac) development system and on FMGo without issue ... but on Windows? Font rendering was awful, mouseover() events wouldn't fire on certain objects ... and the list went on -- a single day before a (Windows-based) demo was due. I never thought FileMaker would be IDIOTIC enough to render using IE8. Rest easy knowing you've saved me from drop-kicking my HP.
