Probably this should be in issue but I think bring it up here first is not a bad idea. What happens is that the Julia exe on Windows lacks the right manifest resources to provide Visual Styles to windows. This issue was brought to me in the Red Gitter where more details can be found, namely that the issue is solved if this manifest is inserted in the Julia.exe, which definitively gives a windows a nicer look.
<dependency> <dependentAssembly> <assemblyIdentity type='win32' name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='*' publicKeyToken='6595b64144ccf1df' language='*' /> </dependentAssembly> </dependency>
Likely this not a Red only related issue.
