Yes, but of course. Are you on a Mac or a PC? I'm actually going now so I won't see your response until tomorrow or possibly Monday... gah.

You shoud either get the options by clicking and holding on the crop button, by selecting the square (perhaps you accidentally have selected the lassoo and have neglected to see the square) or in some versions there is a bar up top where you can select the different versions of a certain tool. Help at all?
If not we'll figure it out.
