Stop After Current problem
Just spent the last hour searching the forums and making sure I was up to date. This has been a problem since version 5 came out. I don't think specs are required.
When using the modern skin and you choose 'Play / Advanced Playback / Stop after current' or hit 'Ctrl-V' the option is in effect and repeating the selection will toggle it back off. The problem is when you view the menu, there is no check mark to indicate the option has been selected. So, if you're forgetful or just old like me, you don't remember if you've already chosen it or not. Using the classic skin shows the checkmark properly.
