Can Mekko Graphics 3 (Professional) open charts saved in Mekko Graphics 4 or later?
Like most standard software applications, Mekko Graphics 4 is forward-, but not backward-compatible with Mekko Graphics 3. That is, charts edited and saved in Mekko Graphics 3 are able to be opened and edited in Mekko Graphics 4, but charts saved in Mekko Graphics 4 are not able to be opened in Mekko Graphics 3. This is partly because the newer versions need to store information relating to features that did not exist in the older versions. If Mekko Graphics were to try and save files in an older version, the loss of functionality in the save would be unacceptable to users. It is for this reason that we strongly recommend all users in an organization be at the same level of software if they plan on sharing charts.
