Having trouble making my game show up in browser

Ok. I made this game. I build it as stand-alone java internet object. I open the htm file to see if its working before I copy the applet code to my web page and it's not working.

In Firefox 5 it just says"MMF Java Applet. Click on the Applet to set the focus." at the top of page and can do anything. In IE 9 it asked if I want to allow the active content and I say yes and then it crashes, closes that browser window or tab and opens another.

I thought it might be elements in my game that may cause this so I made a very simple test game that just has 1 icon that the user can move around in the smallest frame available. 1 frame, 1 object, 1 event lol. I re build it and tried it again and same result as above.

Could it be that my browser doesn't recognize jar objects?

Ok, I updated my java. My game shows up on Firefox and google crome but still crashes on IE.

However, the browsers that do display my game, I can't control the player character. I made the game so the user uses the keyboard arrow keys to move it and it's not moving. It works fine in stand alone on my desktop but in browser no go. I changed the controls to mouse control and I can move the character but cant do anything else with mouse, I have no pointer. So, I can't change windows, or clink anywhere for that matter. I programed it to stop the application if the user hits escape, but that aint working eighter. I have to use alt+F4 to close the browser window.
