Hi. Sorry if this issue has been addressed before; I wasn't able to find any relevant threads when searching. I came across this "security warning" when viewing one of my webpages on Windows XP with i.e. 7 (we're using Coldfusion 8) Internet Explorer - Security Warning Do you want to install this software? Name: Adobe Flash Player Installer I think it is caused by a cfdiv we are using, and flash player not being installed on this particular browser. Maybe it's the "loading" animation that is a .swf that prompts the flash install. Does anyone know of a workaround for this? Would there maybe be a way to replace the default loading .swf with a .gif or something, so that flash isn't needed? ETA: The default loading animation turns out to be a .gif, so it is not the animation itself that prompts the flash install. <script type="text/javascript">_cf_loadingtexthtml="<img alt=' ' src='/CFIDE/scripts/ajax/resources/cf/images/loading.gif'/>";
