SOAP UI not working on my machine

I tried many version of SOAP UI (3.开发者_运维问答6.1,3.6,3.5.1) on my machine but after couple of minutes, my screen filled with bubbles.Not sure, if this tool conflicts with anyother tool on my machine. Please let me know, if anybody has some idea.

thanks Hemish

Perhaps you have the "Bubbles" screen saver enabled on your Windows Vista PC and you are inactive for a few minutes causing the screen saver to display.

Without more information that's the best suggestion I can make.
