<F5> in vim-latex doesn't expand environment

I'm new to vim-latex and have been reading some tutorials. I've noticed that the behaviour of the F5 on my machine is rather different from what the tutorials tell me.

I'm supposed to expect F5 to expand an environment (if the name of the env is typed) or to select from a list in order to expand.

However, all I am getting \usepackage{name of environment} being returned, which doesn't make sense to me of course since I'm trying to add environment tags and not a package.

Why is there such a deviation from the expected behaviour?

Which operation system are you using? Windows, Linux/Unix, Mac, ...? I noticed that the Vim shortcuts under Windows are different as under Linux, which is where Vim comes from. – Martin Scharrer May 1 '12 at 5:20

If you press F5 when the cursor is located outside \begin{document}...\end{document}, latex-suite lets you add packages, i.e. it inserts \usepackage statements. Moving the cursor inside the document section should lead to the desired behavior.
