Hi Shawn,

Your tip works just fine with KiXGUI as follows:

$form.enable = "0" ; to disable the whole parent window
$form.enable = "1" ; to enable the whole parent window

BTW should you use quotes or not?

One very minor issue is that you then need to manually regain focus of the parent window using:

$form.setfocus

However, I now have one new problem in that I can only draw the 'Please Wait ...' message box once during each run time. The second time it is called the program bombs out. Obviously this has something to do with calling $desktop.createform twice with exactly the same parameters. How is it possible to release resources in KiXGUI (I tried using $plswait.closeall but that didn’t work), or should I create the message box only once at the start and just make it visible when required as per Chris’ post?

BTW what are the key differences between Kixforms and KiXGUI, or isn't that a simple question? [Wink]

Kind regards,

Rod.
