Hello,
I'm using 2.1.0 version of Tipp10 with database version 33. In the lesson 6 there are two words that are very hard (impossible?) to distinguish - AI (capital 'i') and Al (small 'L'). Could you remove one of them in the upcoming version?

Thank you very much for your message. We are not getting much response for the English version, the German version is much more popular (don't no why it's so hard to spread it in the US).

That's why your bug note is very important for us. We will remove the bug in the next software version and also in the new online version, which is available in 1 or 2 weeks (you can already register by switching to the German version of our website).

In meanwhile you can change the font type in the program's settings (e.g. to Courier New) that you can see the difference between "I" and "l".
