Thanks for this prudent advice. The case I am contemplating would involve a user creating new substacks to hold content. While I can make sure each substack created by my program gets a unique name, if a file created on one machine is moved to another machine there is some chance of a conflict (reduced but not absolutely eliminated if I went to great lengths, like embedding in each substack's name "the ticks" at creation time). I think I can work around this IF the "substack name conflict problem" is only a problem for the LiveCode UI. In other words if in my own scripts I am careful always to refer to a substack by its long name, am I safe even if two substacks have the same short name? David Epstein --

I don't think it's worth it to try and hack the IDE to get around the warning. You won't lose any data unless you make changes to one of the duplicate stacks and then try to save it. So what I usually do is note the name of the problem stack and quit LC. Then I restart, open the stack I want to change, and temporarily alter its name in the property inspector. I don't save it. Then open the second stack, do whatever work is necessary, and then close and remove it from memory. After that you can change the name of the original stack back to what it was again. When I know in advance I'm going to open duplicate-named stacks, I just change the first stack temporarily before opening the second one. It saves time. -- Jacqueline Landman Gay | jacque at hyperactivesw.com HyperActive Software | http://www.hyperactivesw.com _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
