From a windows 10 PC with Xojo 2015r24 :
I created a program that loads midi files (.mid).
On my PC I have set that doubleclicking a .mid file starts the program.
That works fine.
But once the program is opened and I click on another .mid file a new session of the program starts.
I would like to achive that the already opened session loads this file.
Is that possible ?
