Mouse Cursor Location and Form Behavior on Open

I have a button on a form that raises another modal form.  Oddly (and disturbingly) the form that opens also sinks the mouse click.  So, in other words, the sequence of events is:

1) Click button on Form A
2) Button raises Form B
3) Form B also registers a click

That just won't do.  I don't feel like I should have to work around this with mouse events.  What's wrong here?

For reference, here is (approximately) the code that raises the form:
DoCmd.OpenForm "MyForm", acNormal, , "ID=111", acFormEdit, acDialog, "blah"

Try removing the acDialog and instead, set the Modal and Popup properties of MyForm to Yes.

DoCmd.OpenForm "MyForm", acNormal, , "ID=111", acFormEdit, , "blah"

"Form B also registers a click"

Also, not exactly sure what you mean by that ?

I click the launch button in Form A, then Form B opens, and if there happens to be a button on B right underneath the mouse cursor, that button also gets pushed.

I have a routine that alters the row source of a control on Form B that runs when the form loads.  Somehow that process is messing things up.  If I block that code, the aforementioned phenomenon does not happen.

Well ... guess I would have to 'be there' on this one.  But did you try what I suggested above ... removing acDialog  etc.

Strike that.  I got it now.  There's a control that drops down automatically on enter.  It's also the first control.  That dropping down is the cause of the problem.  I think it goes something like this: The list drops momentarily - then the row source is changed.  This cancels the drop, but Access assumes the drop was cancelled by a click so it looks for the location of the mouse cursor and clicks.

Solved with a new understanding (thanks for that yesterday) of Key events.

Private Sub cbxItemType_KeyUp(KeyCode As Integer, Shift As Integer)
    If KeyCode = vbKeyTab Then Me.cbxItemType.DropDown
End Sub

Instead of ...

Private Sub cbxItemType_Enter()
    Me.cbxItemType.DropDown
End Sub

I really got it now.  You may remember this from yesterday.

"in the end i made two forms for the child table.  one is just a list with no code.  that one gets embedded as a locked subform, for which only two events exist: got and lost focus. if you click on or navigate to the subform with keys, it shows the real editor (the other form) then pushes the focus on to the next control.  it's soooooooo much easier and clear and reliable this way.  and it loads faster. "

So clicking in (or actually, "into") the subform triggers the launch of the form in question.  The subform is locked so the click "in" the subform appears to be a click "on" it.  In this way, it behaves like a button.  But the click ends up getting heard by the form that gets launched.  I don't know what happens behind the scenes, but somehow I suspect if the subform weren't locked, that click might get ignored by the pop up form.  I dunno.  Anyway, now I need to figure out how to work around this.  Bending Access form navigation behavior to your will sure takes a lot of stamina.
