Solve this bug in java combinded with windows7 ( on 20% of pcs )

My programmer has created this game which works fine on windows xp, 2000 and approx 80% of windows7 in mozilla, internet explorer, chrome. However on 20% of windows7 pc it does not work correctly. To see if you have the error please click this link [login to view URL] 1. press start game 2. try to type something in the boxes for log in. If you can type then you dont have the error, if you cant type then you do have the error. Repeat in the other 2 browsers. The 2nd error is that the inner white panel floats around if you move the window ( becomes detached ) In a nutshell this is the error and if you know what it is and fix it you can make yourself a fast profit. Either we will send you the java code for you to correct or you can just explain to my programmer in skype what the error is. It is possible its a bug in some versions of windows7 but i think this is unlikely.. ## Deliverables [login to view URL] requirements notice: As originally posted, this project does not have complete details.
