I'm also having extreme problems with Flash. I did the
uninstaller thing too, I re-booted over & over again & it's
still not working. I can't view anything that uses Flash!!! It
shows up as being installed on my computer, but all the websites I
go to say "you don't have the new version installed-install now."
There's a link to install, I get the pop up on my toolbar to
install Active-X, but nothing happens.
If anyone has new info...please help
