Sweepstakes Ninja | Winners List, Forums, + More!

Here's a sweepstakes that I can only enter with robo. I tried, analyze, fill-in, and the right click menu with Ninja and no luck with any. Is this a bug? it "bugs" me, but I'm not sure it qualifies as a software bug. . . . .

I did not re'install! Here is the problem. If I click on them to check if they are working, and they aren't, and I go back to put the X, it fades and fades and fades... I can't get it to stay! I did NOT reinstall. I close the thing out every day, and re open the next day. HELP!!
