Force single instance of RadiAnt

Is there a way to force RadiAnt to only have one single instance/window of the app?

I often work through multiple images saved as .dicom files one by one. Every time I open up a new .dicom file, a new instance of the app opens up. For my purposes, it would be really helpful if each file could open up into the same instance / window, rather than opening up a new one each time.

Is there a way to enable this? I couldn't see any option in the .xml configuration files that allowed this.

Did you already try to right click on the folder of the dicom files and then clicking on "Open With Radiant Viewer"?

Yes, that does work (as does dragging and dropping all files into the Radiant application).

What I'm talking about is having everything opening into the same Radiant window as a default behaviour (if possible). Right now my temporary workaround with dragging and dropping works, but it would be helpful if there was a setting in the .xml file that I could just tweak to force the single instance of Radiant every time.

Actually there is a hack for this; you need to change the value of the following key in the registry:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Classes\DICOM File (RA64)\shell\open\command

From: "C:\Program Files\RadiAntViewer64bit\RadiAntViewer.exe" "%1"
To: "C:\Program Files\RadiAntViewer64bit\RadiAntViewer.exe" -cl -f "%1"

Awesome, thanks. It's not exactly what I was looking for (it creates a new window and closes the old one, rather than opening into the same instance), but it'll suffice for now. Cheers.
