i used dw4 for a long while and just upgraded to mx. trouble is, i can no longer insert flash elements. when i load a flash document, all i get is a gray box with the flash logo on my display. when i use the flash text button, it lets me begin to create an element, but then doesn't save it and doesn't display it.

i otherwise haven't received any error messages.

is this my fault? or is there something tricky involved? any help appreciated. thanks.
