I'm using the EmbedIt plugin to embed custom code (say from slideshare.net or vimeo.com) into a post or page.
For those that don't know, EmbedIt uses the standard WP Custom fields to hold code. You then reference that custom field in the post.
Since upgrading to WP 2.6, when I paste code into a custom field and click the 'Update' button, it puts one or more backslashes (\\\) around bits of the code (hence it breaks that field). However, immediately deleting that code, pasting it in again (from the clipboard) and clicking update then fixes the problem and all works well.
So it seems to be the first time a custom field is used, under certain circumstances, rogue characters get added which don't get added the second time its pasted.
Any ideas or has anyone else experienced this?
