We are having issues with scroll bars not working when our documents are accessed through certain browsers. IE11 doesn't seem to work. Neither does Chrome 43 but Chrome 52 does seem to work (we have various customers using accessing our documents, so are unable to control which browsers they use).
I have already looked to see if this question has been answered, and a lot of threads suggest that this issue can be resolved by upgrading to SR5. We are on 11.20.12354 SR6 though, so not sure what else to try?
