My messenger signs me out on its own, very very often. Especially when attempting to type. Please he

I'm having some serious issues with my messenger. It signs me out when I try to type in the type box, and signs me out on its own about 15 times an hour. Sometimes it signs me right back in, sometimes it does not. I have virus protection, I've run programs for spyware and adware, and everything comes up clean. Yahoo Messenger is the only program on my computer I'm having a problem with. I downgraded, and am using a very old version, but by using the old version, I'm not allowed to share my photos with people using the new version. PLEASE HELP! Would hate to have to get rid of Yahoo. :(

This may not be the problem of yahoo messenger.This can happen as a result of bad service from ur I.S.P.(internet service provider),that is why it keeps on signing u out and again signing u back.
