sorry, here it is again
this works and behave like expected:
run "d:\setup.exe"
? "press a key"
get $x
$frmForm = CreateObject("Kixtart.Form")
...
it does: - launch setup of Acrobat Reader
- wait a key press
- create a form and so on ...

but this don't behave like expected:
$frmForm = CreateObject("Kixtart.Form")
run "d:\setup.exe"
? "press a key"
get $x

it does: - create form
- do NOT launch the setup of Acrobat reader BUT wait for a keypress
- after key is pressed, it launches the setup of Acrobat !!!!!

I'm using kixtart 4.1.12 and kixforms 2.20 + Windows 2000
