--- Comment #5 from Luke gaming4jc2@yahoo.com 2010-01-06 14:55:09 --- Created an attachment (id=25573) --> (http://bugs.winehq.org/attachment.cgi?id=25573) Log of Paint.NET 3.36 on Wine 1.1.35 suffering same issue.
I just installed Paint.NET 3.36 without any problems on my Ubuntu 9.10 x64 running wine 1.1.35 after using the svn of version of winetricks's dotnet20 install. Then searched the bug database finding this exact same bug.
Free download of 3.36: http://www.filehippo.com/download_paint.net/4572/
The window rendering is indeed borked. The tool windows are all crumpled together and hidden beneath the actual window, resulting in them all being hidden and fairly unusable and the toolbar is totally invisible. Attached it a log of the program running from terminal.
