The test results you have selected are very old and may not represent the current state of Wine.
Selected Test Results (selected in 'Test Results' table below)
What works
Changing language
Searhing/Replacing
Quick Clips
Changing templates and using them
High quality toolbar icons (as opposed to low one in previous test)
What does not
Every opening instance of Araneae gives a Error Log which contains for example:
[10.01.2010 6:50:45]
'x' is not a valid integer value
Minimizing/maximising the window gives only a little box sometimes. Clicking on Araneae on Window List Panel again helps.
Quick Clips->Utilities->Insert Date inserts only an unreadable character followed by ).
Too long vertical scrollbar when there are only a few lines of text.
Adding Linux Tools to Document Viewers might be a little tricky (because the Linux app is trying to open C:\...file. Playing with Drives in wine-config might help).
Titles "Search" and "Quick Tabs" in the bottom have weird, too small, font (quite unreadable), but that is really minor problem.
What was not tested
Printing
Additional Comments
Better, compared to the last test.
It was tested actually on Ubuntu Lucid Lynx development branch (between Alpha 1 and Alpha 2), but I assume there are no Lucid specific bugs (or improvements) in here, but Wine ones.
