Your snippet helped me get to the solution. Still don't know why this works though, as you will see.
So I took your .configure statement and tried several variations in the wording (one can guess at this pretty well after a while, as the documentation on such things is sparse) of the command in the argument list until I got it right. The combobox widget code now looks like this:
self.comboServerMySQL = Pmw.ComboBox(
entry_width=20, # this line not needed
scrolledlist_hull_width=8, # without this statement, drop-down menu is a vertical bar;
# also, if value < 8, no width to drop down menu, even if
# the entry_width is made smaller.
So without "scrolledlist_hull_width", the drop-down menu just turns into a useless vertical line when displayed from a Linux box to a Windows box using an X server. Not good.
Also note, for some weird reason, if scrolledlist_hull_width = 7 or less, the drop down menu reverts back to a vertical line, even though "entry_width" is made as small as 8. IOW, "entry_width" does not seem to affect the fact that "scrolledlist_hull_width" must be 8 or larger.
Why must the value of "scrolledlist_hull_width" be 8 or more???? I have no idea!!
But at least it's working. Proof that the planets do align occasionally. Users of my code will be happy, I reckon! :)
I would think the mailing list might like to know all this stuff.
Thanks for the help!

Maybe explicitely defining the list's width as in this example might help

(though I cannot test it here):
cb = Pmw.ComboBox()
.-.. .. ...- . .-.. --- -. --. .- -. -.. .--. .-. --- ... .--. . .-.
