Motif Application will not refresh

I have a Motif Application created with XtVaAppInitialize . I have two field widgets, created with XmCreateTextField . Now when I programmatically change the data in any of the two fields, the widgets don't get refreshed, only after a mouse over.
I have tried anything, from including the "xrefresh" sources, to including the following code...

XClearArea(XtDisplay(SPMtopWidget),XtWindow(SPMtopWidget),0,0,width,height,TRUE);
XFlush(XtDisplay(SPMtopWidget)); ...

but nothing seems to refresh the Application.
Anone?
I am running Solaris 10 and CDE 1.6.2.

Did you change the text with all the funky callbacks? XmTextField(3X)

No, I used XmTextSetString

Well, google and tinker!

Wow, you are such a great help. Unemployed are you?
