Version: (using KDE 4.3.2) OS: Linux The operating system in which I found this bug is : Ubuntu 9.10, Karmic Koala, 64-bit version. I downloaded "Kstars" using Ubuntu software center. Go to: (From main menu) --> Help --> What's this? this option is blank. Choose it and then left click anywhere on the Kstars screen. Click the hyperlink : send us your own "What's this" help. A pop-up window will appear. I expected to link somewhere, but this is not done. The hyperlink doesn't work. Furthermore this window's title is not visible in all it's length.
I think this functionality comes directly from kdelibs and is not a bug in KStars. Can you try this in any other KDE-app? The link works for me with KStars 1.6.0 on KDE 4.3.95. I get a prefilled "New Mail" in KMail. Either this is already fixed, or you have a problem with your setup.
"Send us your own "What's this" help" sound like Ubuntu specific feature. Bug isn't reproducible and there is no activity for 2 years. Closed as invalid.
