It’s been a while since I installed Canon Digital Photo Professional on Ubuntu / Wine. In the meantime, there have been upgrades to Ubuntu, Wine, and Digital Photo Professional. The good news is that the installed v.3.2 no longer shows the background quirks.
I’ve tried to upgrade to the most recent DPP update (v.3.7.2) as well as the last one supporting Windows 2000 (v.3.4.1) on Ubuntu 9.10 / Wine 1.1.26.You can see the error message above. Given the popularity of my previous post on this topic, I expected it to be known, and I found the bug report in Wine’s bug tracker. Go to the bug report and vote for it to be fixed!
