Once every couple of days, KM will cease to execute any macros (i.e. keyboard shortcuts will not work) for a minute or two. Then after that period all of the macros I asked to be executed via keyboard shortcut come flooding back.
The KM program does not die in this time, it remains viable.
Quitting / restarting KM does not help. Restarting the computer fixes this.
Is a service dying and being restarted in the background; does the system get overwhelmed or what is happening here?
