I'm experiencing problems with my flash banner on a website I'm developing. The flash app sometimes does, but more frequently does not appear in Firefox and ocassionally also in Internet Explorer. The versions of the browsers are Firefox 3.0.14 and IE 7.0.5730.11. It just leaves blank space as if the flash app didn't load at all. I've tried changing several embed attributes, but with no avail. I've developed it in AS2.0 in Adobe Flash CS3 Pro.
I'm currently experiencing it on the system I've build it, but I'm afraid that this might happen on other systems (visitors) as well.
