When many tools are started simultaneously, why does STM take a long time to get back to accepting user commands?
This is due primarily to delays attributable to messaging traffic between tools and STM, which is particularly heavy when tools are first run. One or more tools may even enter a “hung” state during this initialization time, but this should clear up once all of the tools have gotten through this phase. This problem is fixed with version A.06.00 (and above) of STM.
