Hi,
There was a demo floating around but Macromedia were not going to release a CE version free so it never got off the ground. Same goes for Java, its a no go for CE.
Also note that IE does not support activeX controls. Microsoft should call the browser IE6 lite 😉
You can get PDF, PPT, DOC, and XLS viewers but they are created by a third part and are not free. Recent versions of the browser support more image formats like PDM’s
Few, thats about all I know on the CE browser!
