Created attachment 4437 xfce4-netload-plugin-rewrite-widget-creation-and-setup.patch The current state is a bit messy. Widget re-/creation is spread over various functions. With this patch, only monitor_new creates the widgets, while setup_monitor controls which widgets will be shown, and monitor_set_orientation will deal with the orientation of the widgets. I think this way the plugin will be easier to adapt to the new panel versions (>=4.9). Additionally, the event box is set invisible and above its children, so that the context menu is accessible by right-clicking on any part of the plugin. I've wrote this patch after I submitted the patches in bugs #8914 and #8915, so these will be needed to apply, sorry for that. However, this patch has the changes of those two included, so you might simply apply all three consequently before committing and forget about the two older bugs.
fixed in git b6efbf1..e098eaa thank you for your patch
