Hi,
i've been asked this before but no answer
while i have some pictures inside the text and i try to change the position of any of these pictures by mouse, the picture is lost and seems to be deleted!

Internally, dragging is implemented using saving and loading from RVF format.
For RVF loading, the image class must be registered.
The following image formats are registered by default: TBitmap, TMetafile, TIcon, TJpegImage.
For other formats, call RegisterClass one time, when the application starts.

Make sure that rvfoSavePicturesBody is included in RVFOptions property.
Otherwise, pictures will not be loaded from RVF, if you do not provide them in OnRVFPictureNeeded event.
If my guess is incorrect and this option is included, I need a sample document and instructions how to reproduce this problem.
