I know that I have had this discussion directly with you guys in the past. Of course, I can not find reference to it at this point! We have a client who is actively modifying our Display code which creates support (and possibly liability) issues. Restricting Control is easy enough. I can remove all files minus the idb at release time. However, what can I do for Display without having a compiled runtime? I seem to remember some sort of fancy trick using file encryption? All thoughts are appreciated…thanks in advance!
