Fyne doesn't work on Windows 7 VM or remote server #410
Description
Fyne looks awesome, and works great out of the box on my mac. I tried to cross-compile for Windows from my mac, and that generates an exe. So far, so good:
GOOS=windows GOARCH=386 CGO_ENABLED=1 CC=$(which i686-w64-mingw32-gcc) go build
Unfortunately, when I run it on my Windows VM (a Windows 7 VirtualBox VM downloaded from Modern.IE), it gives me the following error that others seem to have.
C:\Users\IEUser\Desktop>fynedemo.exe

I was hoping that this would 'just work' on a bare Windows installation, but that doesn't seem to be the case. Is this configuration supported? What am I missing?
