I'm using CKeditor 4.1.1 in D7.22, and having happily gotten CKeditor working, I have just run into an oddity. I'm trying to add the Asset module to the site, but having carefully gone through the configuration process I seem to have run into a bug somewhere when I try to configure the new Asset buttons into CKeditor. At this point I find that the drag and drop for moving buttons into and out of the toolbar simply doesn't work any more.
I assume that something must be interfering with the functionality, but I can't work out what. I've tried clearing all the caches, disabling the Asset module, using another browser... nothing seems to work.
Have anyone come across this and could you give me an idea of what the problem might be?
