I got around the problem by calling Dialog_Pickfile through an empty
parent widget. I can get it close enough to the screen center that it
isn't too bad. I just wish the size could be specified -- I get real
tired of resizing the dialog when folders contain long filenames...

But, clearly, someone (or something) is doing the centering.
Why can't they expose that mechanism so we can put the damn
thing where we want it?
Cheers,

First, call CENTERTLB, base instead of CENTER_TLB, base
Then, you have to center and realize the parent base before calling
DIALOG_PICKFILE:
base = Widget_Base()
CENTERTLB, base
WIDGET_CONTROL, base, /REALIZE
filename = Dialog_Pickfile(DIALOG_PARENT=base)
I tried various permutations of the widget calls, and that is the only
one that sort-of worked. I'll let one of the other Masters try and
explain why...
