--- Comment #8 from Lisa Denia eiffel56@gmail.com 2009-11-19 19:14:25 --- It is...sort of. The client won't crash anymore after you added a game, but it will show basically nothing. It doesn't freeze(the "File" menu still works, and I can exit normally), but I can't really use the application. I'll attach a screenshot, and wine's output.
Installing Microsoft Internet Explorer 6 via winetricks still solves it. Tested using latest Wine from git on up-to-date Arch Linux x86_64, Wine running via i686 chroot. Winegecko is installed.
