Hello friend, I used to be like you. Frustrated. Angry. Unable to login for 4-5 attempts. Then, I was shown the light, (or at least the letters I needed to type) just by zooming in; puttin' on my cheaters so-to-speak. Case doesn't matter and there are no spaces. Holding CTRL and scrolling-up with the mouse zooms-in to make the Captcha readable. Holding CTRL and scrolling also pops up the option to default back to 100% when done.
