Hi Franks Tom. If you hover your mouse over the verb in this program more often than not a pop-window will be displayed that has a table of conjugations. I am a bit old fashioned also and have a true desire to learn to speak and think in spanish fluently. The conjugation tables are enabling me in my own learning process to learn how to use verbs syntactically/semantically and properly in accordance with the academic rules of this language. Hope this help you out some in your own learning process.
You can't see means that you lack the ability to see. You don't see means you could see but have failed to do so OR potentially can't see. I know it is a subtle difference but I think a logical approach to learning a system is paramount. Learning these small differences can only make one more fluent and precise in my opinion
