Do you have a more practical solution? Maybe Adobe could address the core functionality of the Enable Scrolling feature so that it is viable? Perhaps an update that addresses the general performance of Acrobat, since almost every other PDF annotator on the market seems to run smoothly by comparison. Adobe Acrobat offers some core features that make switching to other software impractical, so it would be nice if that $15/month ($180 annually) actually went to optimizing such an expensive product.
