This is my third post of the day about problems that I am having with Rybka. Thirst post was about the notation being some sort of foreign language instead of English. The second post was about not being able to go into the sandbox from the sandbox buttons. And now I have found yet another problem with this software package!!! In the online tutorial about how to use this package the main menu shows six tabs for the user to select while my version has only 3 tabs showing: Home, Database, & Tree. This definitely is not right!!  There is no generate analysis tab for one thing which means that I cannot even get into analyzing any position using the Rybka engine!  I've got my Rybka 3 Aquarium  CD right in front of me, so I know that I bought version 3, but this version that I installed using this CD does not even do the things that the tutorial says that I should be able to do with this package. I would hope that someone at Convekta can tell me what to do to fix this problem, which seems to be a defective CD!
