Sorry I forgot to acknowledge your info on the locate/find, very much appreciated as I was struggling with the difference. Will try it some time.Opera
I removed Opera qt3 completely and installed qt4 version at the same time.
K-menu item for Opera, this was not replaced or removed, the item was left with non opera icon. I expected either replacement or a new item added.
Opera Icon sent to Panel neither removed or changed (I expected this, as I assume this is a custom setup)
The lonely icon in /usr/share/icons/opera.png has been removed though, and not replaced by the qt4 version.2nd attempt
This time I only removed Opera qt4 completely, found that the Opera k-menu item still in place.
Removed the panel Opera icon
K-menu item for opera I have left, but with non opera icon, I expect it will be replaced or another menu item to be added
Downloaded Opera qt 3 again
Icon opera.png goes into the /usr/share/icons/opera.png
No item installed in K-menu, well not under Internet section, but this did happen the very first time I tried. (none in panel either of course)
Can anybody tell me when installing Opera, if an Opera menu item shows up under the Internet section.
