I have a sVS2010 project in the most recent version of FB 7.0.0.642, in this version I have set Max CPUs : 1
The resulting log shows
Running C:\Windows\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe with parameters : /t:Build /logger:FinalBuilderLogger,"C:\Program Files (x86)\FinalBuilder 7\FinalBuilder.MSBuild.Logging.v3.5.dll" /noconlog /p:Configuration="Release";Platform="x64" /v:normal /m "D:\NightlyBuilds\Bliss\_9SVN\_100908\_Trunk\Bliss9Build.sln"
Notice it is /m not /m:1
Is this a bug or am I doing somthing wrong

Hi
I am unable to reproduce this one here. The action will only pass /m (without a numbered argument) if the Max CPUs option is set to ‘All Available’. Could you provide more information about the Solution you are trying to build (projects included, project types, etc) or create a small example project where you can reproduce the issue and send it to us?
