[New to This]

My problem is that when I click on the Windmill and Dairy Processing plants, I cannot always get them to -- open -- with the first click on them. I usually have to click multiple times before they will -- open (for lack of a better term) -- and allow me to click on produce or store. Can some one please help with this problem?
Thank you to the developers for the wonderful new additions to this great game!! Thank you!!! Thank you!!! Thank you!!!
