Split at Cursor sometimes inserts multiple pages??

Hi,

I've used Sigil quite a bit in the past and have updated to the latest version which is really good. One thing that is a bit odd is that sometimes when I press <ctrl><enter> to get a new page (aka 'split at cursor') it gives me anywhere from one to five new pages.

The expected behaviour would be to get one page at a time. Does anyone know how to ensure that multiple pages are not created? It's not the end of the world but it would be nice to understand why sometimes I get more than one page.

Thanks in advance
