For the most part, W3 Total Cache appears to work for me.
However, if /plugins/flash-video-player/swfobject.js is added to the JS file management list in the Minify section ...
... FireFox & Chrome are OK, only if Line break removal is not checked, and Header (non-blocking) is used in the JS Settings in W3 Total Cache.
... IE8 is NOT OK, regardless of the settings ...
So, for now, I must remove /plugins/flash-video-player/swfobject.js from the list
Any insights as to why there is a conflict would be greatly appreciated.
