In my setup i have a custom system added for commodore 64 covertapes. I thought it would be cool to have the magazine issues the covertapes are from as the manuals. So i added each issue pdf to each covertape as it's manual. Great. So if i view manual from in launchbox, they open as expected. I suspect because they're opening in adobe. However, When i try to view them in Bigbox using the built in pdf viewer, all i get is a blank white screen. This is only with these particular manuals. Any thoughts?
