Harry, Are you setting up the tag list in the data section and then passing the address of it to the OpenWindow() call? If so, then that's probably the problem… remember, the 'myscreen' variable is a pointer (which is what the WA_CustomScreen tag needs). Since it's a pointer, at compiletime, it's a null pointer (it gets initialized by your code after the screen is opened). If that tag took 'the address of a pointer' as the arguement, you could use { WA_CustomScreen, (ULONG) &myscreen } and the compiler would be happy because it could resolve that… but it doesn't, so you need to do something else. I typically use the variable args OpenWindowTags() version of OpenWindow() and pass the tags on the stack. You can pass them all or just a few, with a TAG_MORE pointing at the rest of them. I hope that made sense… Keith
