The problem is you are creating always a new Form (via reflection), this is also not very "fast" so caching the "frm" variable has another advantage

Bastard Programmer from Hell
If you can't read my code, try converting it here[^]

Form newForm = (Form) Activator.CreateInstance(Type.GetType(YourNameSpace + "." + YourNewFormName));

Form newForm = (Form) Activator.CreateInstance(Type.GetType(YourNameSpace + "." + YourNewFormName));
newForm.Owner = this;
newForm.Name = YourNewFormName;
newForm.Show();

1. You create a new instance of the form type;
2. You check to see if there is an open form of the same type;
3. If there is, you call the Focus method on the new form instance;

private Form FindOpenFormOfType(Type formType)
{
    foreach (Form form in Application.OpenForms)
    {
        if (form.GetType() == formType)
        {
            return form;
        }
    }
    
    return null;
}

private void klikMenu(object sender, EventArgs e)
{
    string sFormName = "AIO_System." + ((ToolStripMenuItem)sender).Tag.ToString();
    System.Reflection.Assembly asm = System.Reflection.Assembly.GetExecutingAssembly();
    Type formType = asm.GetType(sFormName);
    
    Form frm = FindOpenFormOfType(formType);
    if (frm == null)
    {
        frm = (Form)Activator.CreateInstance(formType);
        frm.Owner = this;
        frm.Show();
    }
    else
    {
        frm.Focus();
    }
}
