Is anyone else experiencing this?

I have a number of build scripts for different streams, and a couple for the repo workspaces I'm using. Some of the streams are owned by a specific team area, whose process configurations have been set up to restrict access to the stream.

Things appear to go fine - I use the build script to initiate a build, the build manager picks up the request and proceeds with the build. Then, for some reason, builds are left hanging and on looking at the build log the message is

"
2011-03-08 19:15:48 Substituted the following configuration element property variables:
2011-03-08 19:15:48 com.ibm.team.build.maven : com.ibm.team.build.maven.projectLocation = ${team.scm.fetchDestination}\NA - ParentPoms --> com.ibm.team.build.maven.projectLocation = e:\RTC_BUILDS\personalBuilds\axdonn\NA - ParentPoms

2011-03-08 19:15:48 Should build occur?
2011-03-08 19:15:48 Yes: Always build a user initiated request.
CRRTC3527E: Operation blocked by process: 'Control The Build Lifecycle' failed. Permission denied. You don't have permission to perform the following actions:
Start Build (startBuild)
"

And this happens to every stream i then try to build against. I' the only administrator who can change the Process Configurations for the Project Areas and Team Areas, so none of the settings have been altered. Jazz seems to go off on it's own oddessy and ignore the requests.

This tool is driving me crazy.
