Thanks for helping to bring this issue to our attention. I just reviewed item # 111038964688 and I also found that my cursor sticks on the scrolling gallery when attempting to use the mouse wheel to scroll down the page when using Chrome or Internet Explorer, but I did not encounter the issue when using Firefox.
I have not seen this particular behavior before, but I have forwarded the details of the issue over to our technical team for further investigation and I will keep you posted on any additional information that becomes available through this thread.
We apologize for any inconveniences this issue may be causing. If you need any further assistance with your account, please feel free to contact our Customer Support team by mousing over the “Help” tab within your account and selecting the “File Support Case” option.
