Windows is starting to annoy me. Take the following example from a piece of software I am working on. This is a toolbar that should be all on one line.

Can you see the minor problem? How did I get to this? Well, I was clicking to edit the event on the pulldown, and that is what happened? How? Not sure!

How do I fix this? I do not really know. Moving things by hand sort of works, but I think I have missed something. I do not understand!
