Hi, I am making an application using lesstif with multiple threads using pthread.h . My problem is that I have a number of textfield widgets that are managed by a form manager widget. As mentioned before I use multiple threads. One of them handles user interface events, using XtAppMainLoop () and the other one changes the contents of the textfield widgets from time to time using XtVaSetValues, where the XmNvalue resource is set. When doing so, the contents (text) of the widgets is not visually updated. Unless I move the mouse pointer over the window containing the textfield widgets. Has this problem anything to do with the use of multiple threads ? Or is something else the problem. I already tried to solve the problem with XmUpdateDisplay
