Problems with Bat Shack Classic galleries

Word has gotten back to me that some people are unable to scroll through the galleries on the Bat Shack Classic photos.  After you enter the password and submit, the next screen will show six windows--each containing a game.  To the right and left of the six windows there is (or should be) scrolling arrows -- clicking on these will allow you to see a new set of windows (there are five sets of six).  

I do not know (yet!) why on some computers the scrolling arrows are not showing up.  The site is a full screen interface--so trying to shift the entire window a bit may reveal the arrows--I will check with my hosting company on Friday to see if I can get better answers.  

If a simple answer does not reveal itself tomorrow, I will repost all the images in smaller groups, but these will actually take a couple full days.  

My apologies to anyone struggling with this--this is the first time I have encountered this problem and hope to have an easy answer quickly.  ~ Janet
