--- Comment #59 from Paul Romanyszyn pgr@arcelectronicsinc.com 2010-05-28 16:04:50 --- Testing with wine-1.2-rc2 and bug16062.exe
start bug15062.exe from terminal. Minimize terminal. The view on the gnome workspace switcher shows two windows form1 and bug16062. These names are from the mouse over popup. The caption of the only form visible on the desktop is form1. The bottom taskbar shows only bug15062.exe and the terminal session.
After clicking on the minimize icon causes the form1 that was showing on the workspace switcher is no longer present. Using alt-tab or the taskbar sets the focus to bug15062 form but it is invisable.
A quick tests with Delphi 3 ide.Only the hidden top level form is getting focus from alt-tab or taskbar. The rest of the forms are only showing up on the workspace switcher and desktop. So if you minimize any of the forms you can't restore them.
Also replacing the Showwindow with sendmessage no longer allows delphi apps to restore from a minimize state.
