--- Comment #8 from Nikolay Sivov bunglehead@gmail.com 2012-11-22 01:36:34 CST --- Could you try with current wine? You'll need latest version from git wine-1.5.17-256-g2b5ddbf or later. I hope that commit http://source.winehq.org/git/wine.git/?a=commit;h=2b5ddbfe9a39b7c16fb20b33b0... improves the situation.
I will try with Citrix Online Plug-in 12.3 right now to see if it has the same issue.
