Undoing changes to OLE objects (Windows)
You can undo the most recent changes made to an OLE object if the OLE object's application merges commands with FileMaker Pro and if it supports undoing changes.
To undo changes to an OLE object:
  •
Select Edit menu > Undo OLE Object.
The OLE object's application starts, without the most recent changes made to the object.
Note  Applications undo changes differently.
