Very often, when I want to check something (e.g., my credits), the 123RF website asks me to type in a security code that appears as a graphic on the screen.  This is after I have already logged in.  It claims it won't ask me again unless I log out, but in fact it does do so, and often two or three times a day.   Is that happening to everybody, or is it something about my computer?

It appears to be serious security overkill on a website of that type.   My on-line bank and brokerage, where there is a lot more money at risk, don't have anything like that.   I assume it would be a turn-off for buyers as well.
