Get Latest from Perforce

Using the latest version I have configured the source control as Perorce.

I create a new application using the standard application and successfully complete the steps. But when I run it I get the following mesage:

Action 1: Get Latest from depot/TemporaryTestProject/BuildTests/TestWinApp to default directory.Custom Variables: (none)Source and Target directory same; splitting.AgentBasedAction Initialization Complete: Temp Directory: D:\BuildMaster_SVCTMP_A3_S4\TMP Source Directory: D:\BuildMaster_SVCTMP_A3_S4\SRC Target Directory: D:\BuildMaster_SVCTMP_A3_S4\WRK Server: DUB6WSD56001 (Id: 1)Initializing action...Initialization complete.

This should be resolved in v4.2 of the extension: http://inedo.com/buildmaster/extensions/perforce
