Yes, I remember having the exact same problem few weeks ago. I worked my way around it by using CREATEOBJECT() instead of DO FORM in calling the next form. By the way, it is form.name you should use in the syntax, not .scx name.
If you want, you can do it like that yourself.

PUBLIC poForm
* DO FORM... Commented
poForm = CREATEOBJECT(yourForm, < maybe some parameters, if you have them > )
poForm.Show(1)  %% Modal or
poForm.Show(2)  %% Modeless

RELEASE poForm
