The next version of Microsoft's MSN Messenger will offer improved video chat capabilities developed by Microsoft and Logitech.

In MSN Messenger 7.0, due out in the coming months, users will be able to start a video chat with synchronised audio with a single mouse click.

The current version of MSN Messenger offers separate functions for audio and video chat, according to a spokesperson for Microsoft. Audio is available, though the audio may not match the video. This is solved in the new version, which also promises improved video quality, a spokesperson from Logitech said.

The improved video and audio features will be available to MSN Messenger users in the US, Europe, Korea, Japan and Brazil.

Each month, more than 30m of the 155m MSN Messenger users worldwide use the current video chat feature, for a total of more than 3bn web cam sessions served since the service's launch, according to the companies.

MSN Messenger 7.0 is currently in beta, the final version of the product is due in the next few months.
