VBP (64-bit) doesn't terminate at end of build

[kinook]

I guess whatever is preventing the process from exiting normally is also preventing it from being terminated. You might try a Run Program step with a command of

taskkill /f /pid [Builder.ProcessID]

Can you ZIP and send your .bld file and build log file to support@kinook.com? It might give us some ideas for reproducing the problem you're experiencing. Thanks.
