Hi,
In fvwm console appears the following message. What does it mean?

FvwmConsole version 2.6.8
[fvwm][ComplexFunction]: <<ERROR>> Grab failed in function EWMHActivateWindowFunc, 
unable to execute immediate action
[fvwm][ComplexFunction]: <<ERROR>> Grab failed in function UrgencyFunc, unable to execute immediate action
