Sorry for taking such a long time to reply. I had a few family problems (taking care of a sick grandaunt) and didn't have time to test the changes.
The menu is working very well now, thank you very much! I'm glad I could help you in figuring out what was wrong with it. I have a good eye for small bugs, both figuratively and literally. Usually this annoys people, but now and then it can be useful.
A last wish though: I played with the menu in Paint because the lack of a proper closure on top still doesn't feel right. I found that simply adding the missing top border provides a good impression. Compare the first two images below and I think you'll agree. And it could be further improved by having the top right corner with a rounded border similar to the ones in the two bottom corners, even if that'd leave a small blank gap on the line, see the 3rd image. Can this rounded version be implemented? If not, I'd still be happy to get the straight one.
PS.: No, Pisces, and a typical one at that: lots of ideas, most of them of the dreaming type, with an almost complete lack of practical traits. Chinesely speaking, I'm also a Fire Snake, what only adds to my innate talent for annoyance.
