--- Comment #1 from Dmitry Timoshkov dmitry@codeweavers.com 2008-04-05 03:53:49 --- Photoshop CS2 doesn't use child MDI windows anymore as its image containers (as all previous version of Photoshop do), but now all image windows are WS_POPUP ones, i.e. top level windows. Under Windows Photoshop goes into lengthy hacks to trap image windows maximization and reparents an image window. Under Wine its the desktop Window Manager who controls maximization, we can do nothing about it. So basically this is a WONTFIX.
