ECMerge always resumes to the main monitor, how to get it resume on my secondary monitor?

Currently, ECMerge does not memorize the monitor on which it ran last time and therefore resumes always to the main monitor.

One of our users reported that GridMove could be used as a workaround, as you can specify a monitor for a given application. You can download it at : http://jgpaiva.dcmembers.com/gridmove.html. Note, that this software is/was falsely reported as a malware by Symantec and Avast (at least): if you use an anti-virus, please white-list it.
