Was wondering if anyone else is having this problem or if it's just me.....for going on 2 weeks now messenger has been giving me fits.

I used to leave yahell messenger open at nite in case my kid wanted to text me (doesn't cost her anything to do it vs. calling). But in the past couple of weeks yahell has been snapping shut on me when I click on the window to answer any IM's I have gotten. Then it's sometimes 2-3 days before I can even get it to let me back on.....then it starts all over again
Am beyond being amused - it is getting to be a real pita now - have someone who I promised to help with something but also said I wouldn't do anything until I could catch them on yahoo....that was almost 2 weeks ago

I know they think I am just blowing them off since I have had windows with messages from them....but when I click on the window, yahoo closes on me. Just happened yet again in the last 1/2 hour.

Am NOT ignoring them I swear

Any suggestions? And don't suggest using MSN messenger - had bad experiences with it in the past and will not use it ever again.
TIA for any help
