Guayadeque Music Player

I can switch songs with panflute without problem, until song ends and G switch to another automatically. Then I click next song on applet or G, next song starts play, but pointer in playlist jumps by 2 songs. Then is impossible to jump to another song. I noticed that songs have to play for a while

I cant reproduce the problem here using Panflute 0.6.2

Can you explain me step by step how to reproduce it ?

Thanks for your help
