At the end there will be a window 'Help Library Manager - Microsoft Help Viewer 1.0' shown which eats CPU, continuously spamming 'fixme:win:EnumDisplayDevicesW' messages on console. Manual reproduce: --- snip --- $ pwd /home/focht/.wine/drive_c/Program Files/Microsoft Help Viewer/v1.0 $ wine ./HelpLibManager.exe /product VS /version 100 /locale en-US /sourceWeb http://services.mtps.microsoft.com/ServiceAPI/products/ --- snip --- Leaving only one display/monitor enabled makes the GUI properly appear. $ wine --version wine-3.7-136-g8f46ac233e Regards -- Do not reply to this email, post in Bugzilla using the above URL to reply.
