In your Mainstack, as part of it's stack script, can't you have, within a closeStack handler that already exists or just add one:
if then number of lines of openstacks() = 2 then show stack "Mainstack" 2 assumes that you aren't using any other stacks as toolbars or some such and this is in a standalone - in the IDE the number will be much higher depending on what you have open, but easy enough to determine. So assuming you have a standalone with a Mainstack and two Substacks, when you close a Substack openstacks() will report 3 as the substack isn't actually closed until the closeStack handler completes. When you close the last remaining substack, openstacks() will report 2, the Mainstack will be shown and then the Substack will be closed - but it's so quick it appears to be instantaneous. This is pretty basic. If you are using toolbars, plugins or other things so it's not that simple to test the number of openstacks, openstacks() actually gives you the names so a more complex test could be carried out based on the existence or lack thereof of names in the list. As long as your test is carried out in the closestack handler of the stack script of the mainstack, every time a stack is closed you will be able to test if it's appropriate to show your Mainstack.
