Hello,
When using the grouping option in Windows Buttons, the skype button/tab does not blink if I have an unread message from a chat window that is already opened (and I have several chat windows opened, so the skype windows are groupedin taskbar) .
Any solutions for this? I tried settings/windows manager tweaks/Accessibility and check Notify of urgency by making window decoration blink and Keep urgent window blink repeatedly, but this does not seem to work (probably this is a window setting not for taskbar button)
