script/browser error

Does anyone else have problems rearranging and adding items to a list while on a kindle/computer/etc? While using my kindle fire, I had to delete my 1st watching list because when I tried to rearrange and add items the browser had to restart do to a script/browser error. It's weird because I don't have that problem with my other lists. Now it's happening again the same error. Is it because I am using a handheld device instead of a computer, or would I get the same error no mater what device I use?
