Well, after several hours of debugging and tracing, I managed to fix
the modal dialog issue. Then I went to make some diffs to send in my
patches. I decided to pull down the latest daily snapshot to make my
diffs against and discovered that somebody had already fixed my problem!
I don't suppose there's a list I could subscribe to that would send me the
CVS commit comments, is there? If there was, I might have saved myself
some time. On the other hand, tracing through this was a great learning
experience.
My other problem with a dialog growing seems to be something silly
one of our programmers did. When he gets a resize event on the dialog,
he resizes some widgets in the dialog rather than using a form to do it
for him. But resizing the widgets causes the dialog to grow by 2 pixels,
so he gets a resize event and repeat. The fact that resizing the widgets
causes the dialog to grow again is may or may not be an error in Lesstif.
But at any rate, we can fix it in our own code.
