--- Comment #20 from PeterG peter.g.anderson@live.co.uk --- The in-game ticketing system now opens the battle.net login page correctly. I pasted the following update on the bug 38265 thread:
"Tested with wine-staging 2.8, 64-bit WINEPREFIX. Browser functions including game-ticketing are now working correctly in-game."
Suggest both 37594 and 38265 should be marked as STAGED.
