exif corruption with casio ex-p700

Hi,
i'm testing cam2pc (beta 4.5) as image download tool with my new casio ex-p700.
When i enable the options to fill exif data on the fly, the exif data with casio makernotes are lost in the downloaded image.
When disabling the option the exif data stays intact.
Is it intended to work in this way.
Also in some images cam2pc can not find exif data.
With exif-viewer the exif-data is still shown.
Regards
Juergen
