OK; that predates the introduction of the resize restrictions.

This suggests that the WM ought to allow the window to be resized. 
When resize is (intentionally) inhibited, xprop should show:

WM_NORMAL_HINTS(WM_SIZE_HINTS):
		program specified size: 450 by 400
		program specified minimum size: 450 by 400
		program specified maximum size: 450 by 400

Can you try modifying src/display/devices/XDRIVER/XDRIVER24/Client.c,
line 22. Currently, it should read:

	szhints->flags = PSize;

Settings worth trying include

	szhints->flags = PPosition | PSize;
and
	szhints->flags = USPosition | USSize;
and
	szhints->flags = 0;

Let me know which of these (if any) work.
