numbering style

[meorli]

Hello,
I use LyX and the document type is article(ams).
My problem is that suddenly the numbering of both the equations and figures
became nested according to the sections (2.1,2.2 ext.), while I want it to be
in a regular simple order (1, 2, ext.).

Another problem I have is not being able to write the names in the author
environment with capital letters only at the beginning of each word (it writes
the entire word in capital letters).
Please help me on those matters.
Thanks in advance,
Orly
