--- Comment #12 from pvdeynse pvdeynse@gmail.com 2010-12-21 08:05:47 CST --- I can confirm that that hh.exe under wine 1.3.9 does not display the data of .chm files installed in the standard location being ~/.wine/drive_c/Program Files
Problem seems to be with the directory ../Program Files moving the .chm files to any directory "without spaces in the filename" works fine. e.g. ~/.wine/drive_c/*.chm <--- this works e.g. ~/.wine/drive_c/Program Files/*.chm <--- this does not work
wine 1.3.8 did not have this problem. tested on Ubuntu 10.10 and Debian unstable (sid)
