Ok, so I have been testing the WLM and WLMessenger or MSN Messenger 8 Beta. One thing why name a product with three long words, anyway thats MS for you. When Gmail came in Beta, it never had any functionality issues, the core issues where there but they never bothered your routin work. However with WLM there are bugs and more bugs.
Today after 2 weeks of thourough usage, I have unistalled them both. They ate too much memory, made the system groggy and had no substantial improvement over their ancestors.
