Using markers with a tablet

Hi all,

I've used markers in my project, which will obviously show the title when you hover over them and then show the full content, when you click on them.

This works fine when using a PC, but how does the user get the market to show the title only (hover) when they don't have a mouse and they're using a tablet?

I can only seem to click them, not hover - is there a setting I'm missing?

Thanks

Kassy
