>I posted this a few weeks back but was not able to get a fix. I have form 1 that then runs form 2 from a command button. Form 2 is used to change settings on form 1. Form 1 is a modal formset with two forms. Form 2 is a modless top level form. When you click on any control on form 1 the form gets focus and form 2 loses focus. After that, the only way you can get form 2 to have focus is by clicking on the title bar.

>Form 2 has a pointer to form 1 so that when the user changes a setting in form 2 the change is reflected in form 1. (form 1 code: do form2 with thisform. Thisform is then saved in a property of form 2 and it also sets a property in form 1 with its own Thisform.) Thus each form has a handle on the other. It must be that way so each form can change things in the other as needed.

>In place of fixing the problem of not being able to set focus on form 2 by clicking it I thought about simply tracking the mouse pointer on the entire windows desktop and if the mouse is over form 2 then simply have some code set focus to it. I found code at new2news.com but what I found only tracks the mouse position and must be run repeatedly in a loop to get the position.

Try to change "Form 2" to modless "In Top-Level Form".
Desktop property is an option to set "Form 2" out of the "Form 1".
