It appears that a viewported list widget (Xaw) runs into trouble when the height of the total list in pixels (taking into account the font in use) exceeds about 32K. For very large fonts (e.g. "*helv*-34-*") there seems to be a limit of about 16K. Attempts to scroll the list beyond that point cause the list to scroll back to the beginning or be truncated prematurely. This has been observed on two clients running X11R4 (Sequent Symmetry and Convex) and on two servers (NCD19 and Visual 14"). Is this a known restriction/limitation or does it sound like a bug that should be reported? If the latter, would someone please tell me where to send the report and support materials (about 100 lines) and whether there is a standard template to use for the report.
