I am programming an application using the Motif Toolkit. The application runs on top of Open Windows. When a user selects an option from one of my pull down menus, the appropriate popup dialog widget appears. The first time I select a particular command (lets call it A) the appropriate dialog widget appears quickly. Subsequent selections of command A results in the appropriate dialog widget appearing very slowly. I know Open Windows is slow, but this is ridiculous. I want to know why this happens and if there is any way to fix it. By the way I ran my application on top of mwm. The problem I just described does not happen. However, I need to run my application on Open Windows. Thanks for the help. Marianne E. King Lawrence Livermore National Laboratory mking@lll-crg.llnl.gov (415) 423-4116

I haven't tried Motif under "Open" Windows, but I have seen problems with some window managers (e.g. very old (r2 or r3) versions of twm). I'm not sure whether the problems you're seeing with "Open" Windows is due to lack of ICCCM compliance, or whether Motif is expecting special wm behavior. So, perhaps try changing the *waitForWm or *wmTimeout resources. Currently wmTimeout defaults to a 5 second timeout, which may be the slowness you're seeing. From WMShell(3X) man page: XmNwmTimeout XmCWmTimeout int 5000 ms CSG XmNwmTimeout Specifies the length of time that the Intrinsics waits for the window manager to respond to certain actions before assuming that there is no window manager present. The value is in milliseconds and must not be negative. XmNwaitForWm XmCWaitForWm Boolean True CSG XmNwaitForWm When True, specifies that the Intrinsics waits the length of time given by the XmNwmTimeout resource for the window manager to respond to certain actions before assuming that there is no window manager present. This resource is altered by the Intrinsics as it receives, or fails to receive, responses from the window manager. >However, I need to run my application >on Open Windows.
