Case sensitive movie and nfo names

If the .nfo has the same name as the .avi file the program rewrites that .nfo file with its own data and everyone is happy.
However if there is at least one difference in case between the names, when the program is told to re-check the whole folder it assumes that that movie has not been scraped yet and starts all over.
Once the .nfo has had the file name change to EXACTLY that of the .avi file, all is well.
e.g.
Eagle.Eye.2008.avi
eagle.eye.2008.nfo
Media Companion will change the .nfo file to its own structure and save succefully, but it wont rename anything, ie change the e's to capitals.
This is fixed by manually changing the .nfo filename to Eagle.Eye.2008.nfo
Then when the folder is rescanned, Media Companion thinks that the movie must be rescraped.
Very frustrating when this happens to movies that return an incorrect title and you have to continually change movie.

I need some clarification on this,
I created a dummy file :- "Eagle.Eye.2008.avi"
and I created another none MC compliant nfo file :- "eagle.eye.2008.nfo"

It scrapes the movie as expected, the "eagle.eye.2008.nfo" is overwritten with the new xml although it does keep the same lowercase filename, filenames in Windows are not case sensitive.

The nfo is correctly identified by mc and is not scraped again.

What version of MC are you using?
