LyX ⇒ problem with lyx2.0.3ImageFile

[mc2lv]

Hello.
I was up to version 2.0.3 the lyx.
Then, the image of the file had been a huge display.
I was set so as to reduce the screen display.
However, the line is thin and then disappear.
If I convert to pdf, etc. will be displayed without problems.
How to configure metafile2eps, please tell someone how to resolve.
Thanks.
