Does anyone have a work-around for this nasty Silk bug?

I have up-arrow and down-arrow htmlimages on my web page that move selected htmllistbox items up or down depending upon which button you click. Silk hangs after clicking either of these images more than 2 times in a row. I noticed a bug listing in the 5.0.1 release notes #24790 which sounds similar to the problem I'm having. I tried clicking Back/Forward/Reload etc. but nothing seems to work.
