DisableWindow() moves window position

[wombats]

Hi,

When DisableWindow() is called on a maximized window that has a position greater than 0, 0, it moves the window. This doesn't work well with creating modal dialogs.

Code: Select all

Enumeration  
  #Window
  #Button
EndEnumeration

Procedure OnButtonClick()
  DisableWindow(#Window, 1)
EndProcedure
  
OpenWindow(#Window, 100, 100, 640, 480, "", #PB_Window_Maximize | #PB_Window_SystemMenu | #PB_Window_MinimizeGadget | #PB_Window_MaximizeGadget | #PB_Window_SizeGadget)
  
ButtonGadget(#Button, 10, 10, 90, 32, "Click")
BindGadgetEvent(#Button, @OnButtonClick())
  
Repeat
  WaitWindowEvent()
Until Quit = 1

It doesn't happen if you reenable the window right away in the procedure, so I didn't put that in there. Make sure you run this with the debugger enabled so you can quit it easily.

Confirm that the Window doesn't move on WindowsXP 32bit, so looking like a Linux issue (or 'feature').

Doesn't seems to happen here, so may be it's X server dependant ?
