Check Boxes lost when switching pages

Check Boxes lost when switching pages

I am having a problem when trying to merge requests (although this issue goes across all actions) if a request I would like to merge is on the first page (1-100) and I check the box to merge and then if the other request I would like to merge is on any other page (say 101-200) I lose the check mark on the original request and when I hit merge it tells me I must select more than 1 request, (which I know) .
Does someone have a work around for this?
Thanks in advance
