hide / show oddities ?

[Graham Samuel]

Coming a little late to this conversation, I think I have seen this too, in LC 7 rc2. I have several instances of ‘show’ that work, and one, where I have to show a splash screen, that doesn’t. Like you Alex, I automatically thought that it must be something I’m doing wrong, but now I am not so sure. Am about to do more tests. I notice that if I put something that stops the app running (I mean an ‘answer’ message) as the next line after the ‘show’, the shown stack does appear (is visible) behind the dialog box; but without the ‘answer’, the ‘show’ appears to be completely ignored, even if I follow it with a ‘wait’. Gotta find out what this is - it definitely worked in all the 6.x versions of LC.

Although it usually worked OK, in some cases, sometimes, the group would remain visible when it is not supposed to. Trying to find this in the IDE/debugger wasn't getting anywhere, so I reverted to using "put"s (but still in the IDE). I finished up after a few iterations with some code that said
