Once upon a time, I sent you a mail:

Subject: bug in lesstif-0.93.49
To: <[EMAIL PROTECTED]>
Message-ID: <[EMAIL PROTECTED]>
The application using lesstif is the HTML browser 'mMosaic'.
It was under development at that time. It is now expected to
be stable. So I downloaded and installed lesstif-0.93.94 .
Recompiling the application and using it, I found it
shivering when I used the popup menu to go back to a place I
had been before.
Using 'gvd' (gnu visual debugger) I found that the lesstif
function 'XmUpdateDisplay()' in the file 'lib/Xm*/misc.c'
was repeatedly called. The interrupt stopped at line 67: 'XtDispatchEvent(&ev);'.
De-installing lesstif-0.93.94 and re-installing lesstif-
0.93.40, I found that the application did not shiver at all.
So I feel there has been introduced a new bug in a later
version.
I have found a flaw in lesstif so severe that one could
call it a bug. The bug shows up in both versions in
question:
win->toolbar_win = XtVaCreatePopupShell("ToolBox",
xmDialogShellWidgetClass,
win->base,
XmNminHeight, h + 15,
XmNminWidth, w,
XmNallowShellResize, FALSE,
NULL);
#ifdef SHOW_LESSTIF_BUG
form = XtVaCreateWidget ("tear_off_form",
xmFormWidgetClass, win->toolbar_win,
XmNminHeight, h,
XmNminWidth, w,
XmNmaxHeight, h,
XmNmaxWidth, w,
XmNheight, h,
XmNwidth, w,
NULL);
mo_fill_toolbar(win, form, 0, 0);
fprintf(stderr, "\n%s:%d:", __FILE__,__LINE__);
XtManageChild(form);
fprintf(stderr, "\n%s:%d:", __FILE__,__LINE__);
#else
form = XtVaCreateManagedWidget ("tear_off_form",
xmFormWidgetClass, win->toolbar_win,
XmNminHeight, h,
XmNminWidth, w,
XmNmaxHeight, h,
XmNmaxWidth, w,
XmNheight, h,
XmNwidth, w,
NULL);
mo_fill_toolbar(win, form, 0, 0);
#endif /* SHOW_LESSTIF_BUG */
A toolbar in the main window is torn off. A DialogShell
is created and filled to create an external toolbar.
Calling 'form = XtVaCreateWidget();', I found that
'XtManageChild(form);' needs about seven seconds.
Calling 'form = XtVaCreateManagedWidget();' fills the
form as fast as openmotif-2.2.2: immediately.
The antique 'bug' of the xmDialogShellWidgetClass (cnf.
lesstif-*/test/Xm/vendor/test6.c) is still visible in
both versions in question.
Regarding my mail from October 2003: to prevent mMosaic
>from crashing on startup, I had to configure lesstif-
0.93.94 such:
--without-freetype-config \
--without-freetype-lib \
--without-freetype-includes
