Hi! I am running the latest version of Yosemite, DP6, and I seem to have kept bugs for while. On internet reports and forum, I don't see anyone having these specific ones. Not using my computer for a while once, I accidently skiped DP3 and installed DP4 over DP2, I wonder if this would be the cause, where the update I skipped was actually supposed to resolve these bugs. Have you ever heard something like that? If yes, what is the solution? Can we re-install everything? Thanks!
