Reproduce by configuring genmon to run "date" with a period of one second. After clicking close in the configuration dialog, the panel displays the date, but the date does not begin changing once a second until after a signficant delay. This delay varies in a range of about 10 to 20 seconds. The expected behavior is for the display to immediately begin updating once a second. xfce4-genmon-plugin 3.2 - Generic Monitor
Created attachment 1611 patch to restart the timer after the configuration is changed Each time the configuration is changed, the timer is restarted with the current update period. Test with the "date" command and various update periods. This patch also eliminates a spurious update when the plugin is initialized but there is no command configured. This update caused "XXX" to be displayed in the panel.
Patch applied. Thanks
