Ever since I upgraded to Lubuntu 12.04 (from Lubuntu 11.10), the scroll wheel on my mouse has not worked in AbiWord for moving up and down in documents.
The scroll wheel does still work in other applications I've tried--for example, it works in Firefox, Chromium, LXTerminal, XChat, Pidgin, Gedit, Leafpad, and LibreOffice Writer.
How can I restore mouse wheel scrolling in AbiWord?
