Version: (using KDE 4.2.0) Installed from: Ubuntu Packages If you press "Stamp/R Sist" key and keep it pressed for a while (let's say a second), when you release it, infinite instances of ksnapshot begins being created. To stop the creation of new instances I must reboot via konsole.
Kubuntu with kde 4.2.4 I have the same problem with multimedia buttons from khotkeys. My case, I have 4 multimedia buttons, mail, internet, favourites and music. In khotkeys I have configured the buttons with my favourites apps (firefox, kmail, akregator, amarok). Sometimes, random, when I open any app with a button, doesn't stop to open the same app, in a infinite loop. I need killall the application and sometimes It's necessary to force a reboot.

As announced in https://pointieststick.com/2023/07/26/what-we-plan-to-remove-in-plasma-6/ and https://community.kde.org/Plasma/Plasma_6#Removals, I'm afraid KHotKeys has reached end-of-life in Plasma 6. Accordingly, all bug reports and feature requests for it must be closed now. Most of what KHotKeys could do can already be done with the newer KGlobalAccel system in Plasma 6. A few features such as mouse gestures and triggering conditions based on changes to window states are not yet implemented in the new system. These will be added in the future if and when resources materialize for them, and/or when a kind soul submits patches to implement them! :) Meanwhile, the 3rd-party "Mouse Actions" app (https://github.com/jersou/mouse-actions) may be usable for implementing your own mouse gestures again. Thanks for your understanding, everyone.
