Click on a snippet to edit it, or double click it, and click again in the snippet tree, and the snippet editor will open once for each click, including multiple copies of the editor for the same snippet. Since the dialog appears to be modal it should not be possible to do anything by clicking on the composer window while the first editor is open.
I confirm it. Will fix it soon
