Selected Test Results (selected in 'Test Results' table below)
What works
Install completed smoothly. Since Wine 1.1.5 you do not have to set winver to Windows 2000, now it also installs fine with Windows XPsetting.
What does not
Still some buggy behaviour when editing references (see bug 12075). Installing "riched20" and "riched30" with winetricks solves this problem.
Note that the copy/paste commands are ctrl+shift+c (or v).
When using a wine version prior to wine 1.1.5 (which is not recommended) you need to change the windows setting to Windows2000 for the installation. After the installation you can set the winver to XP, Endnote will run with both 2000 or XP.
