FVWMIconMan Icons are focus sensitiv, should be activated only by click

I am using FVWMIconManager swallowed by FVWNButton. Currently the tasks are activated just by moving the mouse on the icon, but I need to change it to click-activation, so I can move over it without activation. What can be the problem?
Code:*FvwmTaskBar: (1861x1, Left, Swallow TaskBarIcons, 'Module FvwmIconMan TaskBarIcons')
*FvwmIconMan*action Click1 N sendcommand Maximize-Func
*FvwmIconMan*action Click2 N sendcommand Iconify
*FvwmIconMan*buttongeometry 120x0
*FvwmIconMan*format %c
*FvwmIconMan*maxbuttonwidth 120
*FvwmIconMan*plainbutton flat yellow black
