The panes in the Datylon for Illustrator user interface are very large and cannot be sized down. Read here how to fix it.
In some cases, most likely when using Datylon for Illustrator for the first time or after an upgrade, the Datylon editor windows are too large and cannot be sized down. Even some of the properties cannot be reached.
The easiest way to get around this is by dragging the Datylon panel into the Adobe Illustrator Properties panel as shown below.
Another option is to go to the Illustrator menu Windows > Extensions > Datylon Account.
The sign-in screen for exporting Datylon templates should appear and can be sized to the right size. The Datylon Editor panel will take over the same size.
