Hi Rouslan and Marc,
I had a quick look at the functionality that you worked on and I noticed
that the font in the dialog is bigger than in the actual page behind.
I'm not sure why this is happening, but I this was happening in my code
as well. To fix this I specified a smaller font-size when creating the
AJAX dialog. For example:
$ajaxDialog = $('<div style="font-size: 0.9em;">'+data.message
+'</div>').dialog({ /* options go here */ });
