I discovered that I can't select directly in the game the planet I colonize. I must select it in the empire tree or make a selection box, it's a bit annoying and take more time to manage my colonies.
I have to precise it works well for my homeworld : the icon has a yellow circle when I click on the planet or the icon.


I added a serie of screenshots to show the problem(the cursor was added after the screenshot but tht just an example) :
1 - homeworld with cursor out
2 - homeworld with cursor on planet, works fine
3 - colony with cursor on planet broken
4 - selection box on colony works
5 - selection by empire tree works
