Here is what we do:

---

lcCaption = "Your Program Caption Here"
Local lnHWND
Declare INTEGER BringWindowToTop IN Win32APi INTEGER
Declare INTEGER FindWindow IN Win32Api INTEGER, STRING
lnHWND = FindWindow(0, lcCaption)
If lnHWND <> 0
BringWindowToTop(lnHWND)
Return
Endif
_SCREEN.CAPTION = lcCaption

---

This has worked well, it even brings the application to the front if its already openned.

I'm pretty sure I got this code segment from UT files section.

Hope it helps,
