About updating agents
The workaround is to force the agent to update doing Get Info for the agent you want to update, selecting agent in the left column, putting your cursor inside ht Query field, and then adding or subtracting a space.
Just add a space. Next time, remove it. Changing one byte is all you need to force an update.
This works like a charm, and avoids the slowdown that comes from doing File > Update Agents Now.
