I am using Beamer class for my presentation. After inserting
\begin{block}{myblockname}
.
.
.
\end{block}
The default spacing on each slide is single-space. And this is true before the block/box part of the slide. The spacing after the block is no longer single space. As a result my text that I wrap on the slide after the block/box falls off the slide, b.c. for some reason it defaults to a wider spacing than single space. How can I revert the margin space setting to single space after the block.

ThankQ!
