Problems with flash

Using Seamonkey under Win8, Flash crashes every time I move the slider or a video or clack the pause. Under Win7 all worked well.

Does Flash work normally in IE ? If same issue, reset IE. May do a reset anyway just to see if any effect since Flash is built-in.

Also, may try to check with Mozilla Forums.

The flash games (such as Sparta) do not work, flash crashes.
