I am attaching the project.
On the first form there is a button to open the second form.
Also on the first form there is a checkbox to set/remove the fsSystemStayOnTop style.
If the second form is open, then uncheck the checkbox hides it, and then it is no longer possible to open the second form.
What is the problem?
