Ever since I installed Flash Player 8, Opera 8.51 has crashed on me every
single time it tried viewing flash content.
Firefox 1.5 tells me the Flash plug-in performed an illegal operation whenever
I do the same.

When I uninstall Flash Player 8, MSIE 6.0 still displays that it's got FP8
installed, and Opera or Firefox hasn't changed at all.

I use Windows XP SP2.

Have the same problem, however only using IE and Firefox 1.5.
Getting that message but it dont crash, well not until a lil later on. just
says it hit an illegal operation from just loading a page containing flash.

Windows XP SP2 here aswell.

Most annoying is what is mentioned in Tphlosion's post. that even after an
uninstall of BOTH programs (shockwave/flashplayer) they still seem to be on our
systems, are your uninstallation programs really working?

I am having the same problem. I have installed and uninstalled both the plugin
and the browser several times. Weirdest was when I uninstalled the browser,
then reinstalled it clean, and still showed a flash error... flash should have
been gone with the browser uninstall! I manually uninstalled flash and
reinstalled, same errors continually. Please fix!

Flash can be disabled in Opera and Firefox by deleting the dlls in the plugin
folders (Opera/program/plugins/NPSWF32.dll and Firefox/plugins/NPSWF32.dll).

Still, this should be done automatically when one uninstalls the player!
And it does in no way change the fact that the plugin is messing up both
browsers when present.

Same problems here, win XP pro SP1. Any solutions? this is irritating!
Thanks!

My operating system is Windows 98SE

I have the same problem, regarding the installer going into the background and
illegal operations on every site with flash. The weird thing is that if I hit
refresh about 10 times after getting the illegal operation message, Flash will
display just fine. Tech supprt will not reply to any requests. Nobody at the
Mozilla forums has a clue.

I have the same problem. IE6 crashes as soon I try to view Flash content with
flash8.ocx. One member (have a look thro the forum threads) found that unless
you accept the "free" offer to download the universally hated Yahoo searchbar,
Flash8 will never work. It could be deliberate software crippling by Adobe and
Yahoo.
Hard to believe that a comany like Adobe is not capable of finding a software
programmer out there who is capable of fixing this problem.
Instead they trot out a post that is a year old! Incredible!
