Thanks to a couple of members of the Coco Community, we have now resolved the permissions issue with the "VCC.ini" file and it has been moved to the user's "appdata" folder where it can be altered without administrator's privilages.
Also, the "Force Aspect" item in the "Config/Display" menu now works... HOWEVER, it does not work in full screen mode (this is being worked on). You must activate (check) "Allow Resize" and "Force Aspect" then you can drag the edges of VCC to the desired size and it will maintain the proper Coco size aspect. This also works with Windows screen "Maximize"
I have also updated the VCC manual to reflect these changes and have tried to correct all version # conflicts :-)
