Error Message Related To Screen Resolution When Opening Yahoo Mail, What Could It Be?

I also had this problem.  Eventually, I discovered that Yahoo Mail wanted my browser window to be full screen, not the slightly smaller window I was using.  Setting browser window to full screen before Yahoo Mail log-in did not get the error message.  After log-in, I could then reduce the window size and continue normally.  What a pain !!

Anyone having a problem with a "screen resolution" when trying to get into Yahoo! Mail?  Twice in one month I had the "screen resolution" message.  The first time I was able to "continue" and get into my Inbox.  The second time, just the other day, I couldn't do anything to get in using my laptop.  (My tablet and other laptop worked just fine.)  So, it had to be something with my one laptop.  I went into the display settings but the res was better than required.  I FINALLY found an answer on the Mozilla site.  (The problem occurred when I used the Firefox browser.)  Someone said to "unzoom" the screen.  So, I tried "control" and the "minus sign" and it worked!  There are other ways to reduce the screen - control and zero works too apparently.  I think I accidentally zoom the screen sometimes because I rest a finger of one hand on the track pad while navigating with a finger on my other hand.  I've caught myself zooming the screen inadvertently.  So, it wasn't an ATT Yahoo problem - it was caused by the user, ME!  Anyway, problem solved, and I am SO happy.

Another reason to scrap my yahoo accounts. Can't bother. They trying to plant a bug in my pc....:(((((

Same with me -- just started after I upgraded Firefox, and my screen res. Has always been 1600x1200.  I also have XP-pro.  Yahoo and Firefox have another glitch, I guess.

I have the same problem.  Why doesn't Yahoo tell us what is going on?  I am using a netbook; adjusting to the resolution they recommend in the message results in cutting off part of the e-mails on each side so that horizontal scrolling is needed.  

My resolution setting works just fine on GMail, without any screen res messages.  I have to use the "go to Yahoo mail anyway" click when I open Yahoo.

Could someone from Yahoo try to answer this question?  It has been asked repeatedly elsewhere, too, and the only answers are like this one: "I have the same problem."
