I too, see this problem. Default template wouldn't load at all 
untill I clicked refresh for each page change. 
My template would load, but not a empty folder, untill I 
clicked refresh. I noticed the address bar didn't show the
empty folder untill refresh. Changing the charset=UTF-8 to
something else solved both templates here. I know ie6 is
pretty substandard, but its also still widely used.
