Hey,
This mod for GW makes it flash like Messenger whenever you receive a whisper and Guild Wars isn't the active window.
You can read more about it in this post on guru:
Installation:
- Unzip the FlashMod.zip and you'll find a file called Graphics.dll
- Copy Graphics.dll to your Guild Wars folder (where Gw.exe and Gw.dat are located - in most cases C:\Program Files\Guild Wars\)
- Start Guild Wars (or restart it, if it was already running)
Hope you like it
