MSN Messenger 234x60 expanding ads should be built using the same Microsoft Rich Media MTK framework as other expanding ads, but also need to follow these specific additional guidelines:

1. Banner frame label must be placed on frame 4 or after.
2. You must use framelabels "banner" and "expand".  Using _root.conduit.banner(); and _root.conduit.expand(); to expand/contract the swf will not work in Messenger.
3. A stop frame is required after the frame label has been hit. Expanding/contracting an ad will cause the playhead to play from that frame label (if banner state is on frame 4, a stop() command should be put on frame 5 to prevent the ad from hitting the expand state without rolling over).
4. When using child movies, they must be loaded from the key frame where the phase label resides. It is required to unload them on mouseRolledOff();
5. Expansion phase starts immediately at full dimensions. No slow expansion (expansion animation).
