[Windows Live Messenger] Intermittent hanging

Anyone encountered intermittent hanging of Windows Live Messenger on Win 7? I've been getting that on my main system which will render WLM usable for around 15 secs then hang for around 6-10 secs. Other apps work fine during the period when WLM is "hung".

2 complete reinstalls of OS and trying out an earlier version of WLM does not work.

Using the latest version of WLM 2009

Any help will be greatly appreciated.

I am facing Windows Live Messenger hanging problems. often when I start to send messages it stops responding for 10~15 seconds then its hangs in typing the messages.

I have Windows 7 Ultimate and WLM Version 2009 14.0.8089.726

I think it may be because of Windows Defender as the problems occured more frequently after updating the Defender definitions 1.71.26.0 KB915597

I have disabled the Defender for now on lets see if it works.:huh:

Live Messenger hangs on all platforms it runs on, incessantly. It's bloated adware that I wouldn't touch with a bargepole personally as all my contacts are quasi-permanently disappointed by it's freezing, crashing, failed file transfers, poor consistency of video and audio, and periodical forced updates.

Logitech vid' does far superior 1:1 video chat, and there's absolutely no risk of virals

the funny thing is that it only happens on one of my 5 machines, ironically it is the most powerful machine of the lot.

Intel Xeon X3360 Quad
8GB 1066 DDR2 HyperX
Gigabyte EP45 series Mainboard,
Geforce 9600GT
300GB Velociraptor.

Still its hanging the system and specialy when new chat window opened it hangs for a while.

I did the following but no results

Defender Disabled.
Games for Windows Update Installed - LIVE 3.1 (if it may link with messenger)
PC Tools Antivirus Installed Version 2009 (free edition) in place of Avira Free AV
System set on High Power Mode

Are you running any addon programs with it like Msgplus live or MSG discovery?
