My background is flash animation/development and I decided to start working on my first html+css+js site. The site works great on FF, Chrome, Safari both platforms.  But on ie the animations do not run smoothly. I narrowed the bug but have no idea how to fix it.  The bug appears to be the plugin.js files that I call. If I have no plugins the animatons work perfect but every plugin that I add slowly kills the animations.
