[Gambas-user] Disabled controls still react to events

I've been away from the list for a little while.  I finally got the time
to download the latest version of Gambas (0.70b).  I have a problem that
I need help with.  I do not know if it is a problem with my
understanding of the qt library, or a bug.  When I try to disable a
button while a long running process is running the button does indeed
ignore the click event.  However, after the long running process has
finished, any click events on the disabled button is processed.

To see what I mean, create a form with a button called btnProgress and a
Progress bar named pbrMyProgress.  Copy the following code into the
form's code module.  Run the program.  Click on the button.  While the
button is disabled and the progress bar is running, click on the button
a second time.  After the progress bar finishes the first round, it will
restart as the second click event is processed.

Also, I am still having trouble with code windows not wanting to close. 
When I click the window close button on the window manager's form
decoration, the window flashes, but does not close.  I thought this was
fixed a while back?  If you need machine specific info for this problem,
let me know.

PUBLIC SUB btnProgress_Click()

  DIM iCount AS Integer
  ' Disable the UI while we work
  ME.Mouse = Mouse.Wait
  btnProgress.Enabled = FALSE
  WAIT  ' Allow the components to redraw as disabled
  ' Do our "Work"
    pbrMyProgress.Value = CFloat(iCount) / PROGRESS_MAX
  NEXT ' iCount
  ' Re-enable the UI
  btnProgress.Enabled = TRUE
  ME.Mouse = Mouse.Arrow
