I've always felt, that if a driver worked one day, then it should still work the next day.
In thirty years, I've never fixed a computer by updating a driver. Maybe just dumb luck, as some would call it.
But when my own browsers started acting up, one day, I knew it had to be something I had installed after the last browser was installed.
Sure nuff, it wound up being the "Flash", that I had installed after Firefox.
I use it all the time, on every OS from XP-Home to Win-7/Ultimate/64, with narry a problem.
To totally fix the damage, I just re-installed Win-8/64 and all's working well again.
It's sort of amazing, how many different things can cause the same type of problems.
Cat, I'm glad you got your problem fixed.
Cheers!
