Thanks, Johannes and Wayne.

Having the single-instance listener switched on by default (like in ImageJA) is a good choice. Also Mac and Windows behavior will be the same.

Currently, if Windows is set to associate ".tif" files with ImageJ, each double-click on a ".tif"  file opens a new ImageJ instance (unless the user explicitely has checked that hidden checkbox).
A new user may not even be aware of this complicated situation - nor understand the "Instance" checkbox hidden in Edit>Options>Misc..
So hopefully the default will be set to "single-instance".
