Changes made (afterwards) to template don't apply on blogs which are using the template

Hi Support,

Today I've worked with the 'New Blog Templates' plugin. Looks good so far. But now I worked it all out and my specific needs are that when I'm making changes to the blog (afterwards) then they have to apply to all the blogs (sites) which are using that specific template.

But when I make changes to it, they don't appear. So is this plugin only for 'static' themplates and you can't make changes afterwards to apply on al blogs?

Hope to hear as soon as possible.

Regards,
JJ
