The attached text app contains 3 forms... (the buttons are for your convenience)...
Using OpenMode causes the identified OpenMode Form to be opened when the app opens, in addition to what Form is scheduled to open... it doesn't seem to have any impact on whether the Container shows or not.
The Form with the Container NEVER shows the container regardless if I use the
or not. (a hopeful workaround for this is to set up a Form that just contains the Container and never reference it except for the appendChild code...I suspect I can set that to OpenMode, but hidden, so I don't get the problem noted in the second paragraph above.... interesting aside... when the OpenMode Form opens, it opens in 'double size', regardless of the ScreenMode setting).
the bigger issue is that the appendChild only seems to work on the LAST Form... e.g., with three Forms, each with the AppendChild code, Form 1 is no show (of Container), Form 2 is no show and Form 3 shows Container.... I blocked commented Form 3 out and now only Form 2 Container shows (vs. a no show if three is active.)
