Running ADE 4.0.3 on MacBook Pro running OX 10.10.2
Downloaded local library title via OverDrive; clicking on it launched ADE, which displayed the title.
Tried to read the new title (clicking on it; then tried selecting Read from a menu) and the application just closes - slinks away.
Please download the latest ADE 126.96.36.199137
Some of the crashes have been fixed in this release.
Thanks for being the part of product improvement.
