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)
OS: openSUSE 11.4
Installation -- good
Importing of QDF and QIF files -- good
managing accounts -- good
printing -- good
adding and removing transactions from register -- good
What does not
Restoring from a Previous version backup - fails during conversion
Quicken wants to contact webconnect on each start up. May need to adjust some registry keys.
Visuals are poor. Some dpi qualities with text are inevitable. Some text is barely legible, some area cross over each other. Occasional scroll will leave ghosts of previous images over top of new image.
Wine graphics options don't have all that much effect.
What was not tested
Did not test what was not mentioned.
Overall it works good - Requires fine tuning, lots of fine tuning.
Very easy to install and get your old files on it. My suggestion for those ugrading - Install on a Winbox first and upgrade your data file, backup up and use that new backup for Linux Quicken install.
