And as I remember that function works as I want before few upgrades. Normally I was using key shortcut and my source lister was open in destination (something like "duplicate lister" but using listers that are already open). Normally that works on separate listers (I do not use dual) but now the same function make my lister dual instead of copy path to destination lister. How can I improve that command to work with existing versions of Dopus on separate listers?
Don't think those will help, except maybe to close the unwanted dual-display. They won't make the separate destination window do anything.
As far as I can tell, from a very quick look, it seems like OPENINDEST is behaving the same as OPENINDUAL, which doesn't seem correct. I've sent GPSoftware a support request about it.
I can't tell you as I don't know. You'll have to ask GPSoftware if you want to know those things (if they have even looked at the issue yet; it's only been a day since I reported it to them), or just wait for the updates and see what's in them.
