Reproducible in 1.7.33.
A workaround for the drop-downs is click on their headings eg. 'File'.
A workaround for game context menus is to click on the menu headings 'Actions', 'Mentor', 'Preferences' or 'Windows'.
Does this bug affect Chessmaster 11 as well?
Yes. Reproducible in Chessmaster 11 with Wine v1.7.33.
For those who don't know, the GUI between Chessmaster 10 and 11 received very few changes, so if there's an interface bug in Chessmaster 10, it's more than likely in 11 as well.
