I didn't understand how to do that. Prompt with tech selection constantly appeared. I tried it again with success: select any tech from prompt, go to F6 advisor and click to discovered tech to avoid putting beakers into any particular tech. Now I checked it myself. Tnx! It is interesting to be able to delay selecting of particular tech for a few turns - exploration of area may help you decide which path you should go. Can we put together another thing? Does the capital border expand on the same turn when you allowed to delay tech? In other words can we wait till border covers the fat cross for the better choice?
