just tried teh registry hack, settings literally are not working and I literally despise the flashing icons as it breaks the "hide taskbar" option as it keeps flashing and refusing to vanish so I can type replies in a current chat window until I look at the other chat window
in fact it seems to be a recent PROBLEM for ALL chat based apps, to flash the taskbar without giving an option to "just never flash the taskbar" in each program, and windows is so shit that it doesn't respect it's own settings app when you tell it NOT to do something, and I am pretty sure it even ignores "focus assist"
suffice to say, taskbar flashing was ALWAYS an UNWANTED feature by EVERYONE
yet microsoft just doesn't care what actually makes users like them, they haven't all the way back to win95/dos days, they literally lost an anti-trust lawsuit over their literally terrible and worthless ie browser when the first GUI OS'es were being devolved, and they never learned their lesson to LISTEN ONLY TO USERS NOT MARKETING
