We have a site set up that uses a lot of Text/HTML modules.  From time to time a module will begin to cause client side stack overflow errors while in the edit mode.  Once that happens, the only way to get it to stop throwing those errors is to delete the module and retype everything that was in it.  According to my business customer (who is actually experiencing the problem), copying and pasting the contents will not work.  If that is tried, the error repeats itself.  We are currently using 04.08.04 with IE 6 and 7.  Any help would be greatly appreciated!

Strange,  I've never heared of such a behaviour before.
