set FORMS_MDI_WINDOW width is limited with FSAL and not with javaws

SFrixJun 24 2022

Hi,
We have Forms application in version 12.2.1.4 under Windows server. User computers are Windows machines too.
Context:
We have several forms modules with standard size (defined by us at design not by program) and, using stacked canvas, we give the possibility to the users to access to more columns than our standard allows (by scrolling horizontally).
Need:
I'm developing a feature allowing the user to increase horizontally the size of the window (by increasing width of MDI window, window, canvas, ... and moving vertical scrollbar).
Issue:
This is working fine when I launch the application using Java WebStart. I can increase without limit the size of the MDI Window.
When I use FSAL to launch my application, MDI window increases until it reaches the max size of my physical display. The code does not fail but the MDI window stop to enlarge. When reading the size of the MDI after I increase it give a corerct new value but it does not correspond to what I can see on my screen.
Code used to increase is :

set_window_property(FORMS_MDI_WINDOW
		  , WIDTH
		 , get_window_property(FORMS_MDI_WINDOW, WIDTH) + l_default_step_size);

Is there a configuration parameter (in formsweb.cfg) I missed that can change this behavior ?
Thank you in advance and let me know if it is not enough clear or if you need more info (I didn't want to put useless info or setting so don't hesitate to ask me)
Sebastien.
