I would like to use \begin{theorem} \end{theorem} in an itemized list in beamer. Unfortunately, this messes up the indentation of the itemization, and pushes the item sign to the far left of the page - it seems that Theorem has a fixed position, and the item sign gets on the left of it. In other words, the theorem environment seems to define the layout instead of the itemization. Is there any way to change it?
I would also like to change the colour of how Theorem appears.
