LyX ⇒ Figure Numbering Style Problem

[majidraf]

Hi,

I'm a newbie in LyX and I'm using LyX 2.0.0 in IEEEtran template. The figures number are like this: "Fig III. A" which means figure is in section III and subsection A. But I don't like this style and I have to change it to the normal one, like this: "Fig 1". would you help me please to know how can I do this?

My second question is about LyX 2.1 on Windows 7 (64bit). When I upgraded LyX from version 2.0 to 2.1, it got an error that LyX cannot find PDF file in temporary folder. I uninstalled LyX 2.0 and install 2.1 again but same problem existed. After installing LyX 2.0, the problem was solved. Is there any defect by LyX 2.1 ?

Any help will be appreciated.
Thank you.
