Dr. Sinclair, Looking at the list of supported controls that can be enabled for Drag and Drop, I don't see a DB Image or Variable Image on the list. However, feel free to submit an enhancement request for R:BASE eXtreme v9.0 (64) for .RX? databases and R:BASE eXtreme v9.0 (32) for .RB? databases. http://www.rbase.com/rbg9rdcc/ Remember, nothing is impossible! Meanwhile, enjoy the latest versions and updates of R:BASE 7.6 and Turbo V-8 for Windows. Very Best R:egards, Razzak. >-------------- Original message from "A.
