This is not a launcher or Unity bug. And it's still relevant for the latest Ubuntu version (13.04). Take a look at the *.desktop file of jEdit (it's a text editor written in Java and ships in Ubuntu's universal repository).
First of all: create a copy of jedit.desktop and modify all the relevant entries. Most of them are relevant. :-) Now the problematic entry is StartupWMClass. If you don't set up this correctly, Unity won't be able to "identify" the process/window that is launched by the executable specified by the "Exec" entry. You can start up SQuirreL and use xprop to get the correct value. I'll help you: it's "net-sourceforge-squirrel_sql-client-Main" So a proper squirrel.desktop file looks like this: [Desktop Entry] Name=SQuirreL GenericName=SQuirreL SQL Client Comment=Browse/edit SQL databases Exec=/opt/SQuirreLSQLClient/squirrel-sql.sh %U Icon=/opt/SQuirreLSQLClient/icons/acorn.png Terminal=false Type=Application Categories=Development; StartupNotify=true MimeType=text/x-sql; StartupWMClass=net-sourceforge-squirrel_sql-client-Main Keywords=Programming;Java;SQL (Of course assuming that SquirreL is install in /opt/SQuirreLSQLClient) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/878113 Title: Custom launcher for SQuirreL starts new process on every click To manage notifications about this bug go to: https://bugs.launchpad.net/bamf/+bug/878113/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
