Likely. But it may not be an ESS problem per se. M-x R starts a process that runs asynchronously. In interactive use there is no issue (barring something in .First() that slows the startup for a very long time). But, ... If the (rename-buffer ...) in org-babel-R-initiate-session runs before all the setup that ESS performs in the process buffer is complete, chaos can result. Not sure what the best way is to fix this. A simple hack to temporarily solve the OP's problem is to force a pause before (rename-buffer ...) with (sleep-for 0.1) or something. HTH, Chuck
