Different status for Read Object Status of Form0 vs other forms

[timbotimbo]

For my application, I've chosen to poll all of the forms that have been implemented. I have Form0...Form4.

My goal is to implement a function that can determine if a particular form is displayed or not. After some experimentation
I found that by reading object status for a specific form results in a report object status msg with LSB value set to 1 if displayed or 0 if not displayed.
The documentation does not specifically indicate this is the way to poll for active forms or state of a form, but I thought it reasonable and through
experimentation have come to this conclusion.

It doesn't appear that Form0 responds this way. When I poll for all the other forms (form1...form4) I get
the desired effect. However, reading object status of form0 always returns 0 in the LSB.

I would appreciate confirmation that my conclusion is right and why it may not work with form0?

If this is not the right approach to poll the state of a form, how can I determine which form is active, without using ReportEvent for each form?

thanks

Update

Upon further experimentation it appears that Read Object Status on a form ignores the object index and returns a Report Object status with the active form's object index....even better if this holds up.

That is what it is designed to do, so it will 'hold up'
