First of all, well done guys, the R4 is really worthy and I´m happy on buying it.
>> With the example composition (windows), that came with the beta installation, while trying to change the default comp resolution to any other, like 800x600 for example, the Output monitor just went blank, and the videos are only available to see in the preview window.
First I thought could be something with resolutions at all, but it works well with a fresh new composition with differents resolutions sets.
