Still plugging away with some tests in Opera. Decided to continue with the thread to keep items in same place.
From reset K-menu, good menu system
From K-menu placed Opera in Panel
Used Panel Icon Properties
Changed the command: "opera %u" to "opera %u -newwindow" (%u seems to have no effect)
Result removes K-menu Opera item, and the Panel icon is replaced with ? in Opera icon
Panel icon with ? remains
Using this panel Opera (?) icon will start Opera Window with proper Icon showing in taskbar picture 10
File content is intact and the file starts Opera
Reset the K-Menu and the Opera back in K-menu
With K-menu Editor changed the "opera %u" to "opera -newwindow"
The first Opera window instance opens with Speed Dial Tab as I like
Second Opera instance opens but Speed Dial Tab missing, a bare Opera Window without a tab
Easy to add the tab
Added Opera to Panel
Checked operation is successful, Opera windows open as above
I am still undetermined as to how Opera ought to open. If I don't allow Opera to be grouped it is easy just to drag Opera to required dekstop but I will have to move to this desktop as a second click to use the Opera instance now here. One extra click.
At this stage Opera will only open in dt-6
