I'm having a problem using TWM with an application, and I'm wondering if there is a bug in TWM I'm not aware of. I have an application that displays an XImage in a Viewport Widget. There are several pop-up menus associated with the widget that are all created as children of the toplevel and are all transientShellWidgets. The problem is that whenever I pop-up one of the menus over the image, the image isn't refreshed when the menu is popped down. I'm under the impression that a widget created with XtCreate- PopupWidget, should take care of refreshing the screen beneath it whenever it is popped up and down. I also have other widgets on the display and whenever the menu is popped up over any of these, it is restored upon pop-down. Is there something I should be doing to preserve my image each time I pop-up the menu? I have run the software under UWM, and I do not have this problem. That's why I thought there may be a bug in the TWM software. I'm running this on both a Sparc-1 and a 3/60 (SUNS). I have X11R4 patched upto 11 on the Sparc-1 and upto 9 on the 3/60. All the widgets in the application are from Xt or Xw. Please help. I've been puzzled over this for some time now, and it's beginnning to drive me crazy! Thanx! Nancie P.
