Try p. 3-54 in the V3 IDL Reference Guide; the X resources
idl.olh_text_width and idl.olh_text_height (measured in units of
characters and lines, respectively) can be put in either
DECW$SM_GENERAL.DAT or (you can create) DECW$XDEFUALTS.DAT.

Try adding the following in the DECWindows Motif equivalent of ".Xdefaults":
idl*olh_text_width: 70
idl*olh_text_height: 25

The CORRECT answer should be in the FAQ. I've seen this behavior with other
IDL widget programs. Apparently the problem has something to with the widgets
being too big to fit on the screen, so the Motif window manager gets confused.
One workaround was to use a smaller font size using
IDL> WIDGET_CONTROL, DEFAULT_FONT=myfont
but I don't think this has any effect on the ? command.
I've heard that there are supposed to be some commands you can put in your
.Xdefaults file that solves this problem, but I don't know what they are. I
couldn't find any documentation on this in the release notes, but maybe it is
documented in some of the newer manuals.
