Hi,

and the documentation to Button doesn't help?

 >>>
Typical possible settings for the  Method option include  "Preemptive"  
and  "Queued".

With the default setting  Method->"Preemptive", button actions are  
performed immediately, preempting any other evaluation, but are  
allocated only a limited time to complete.

With the setting  Method->"Queued", button actions are added to the  
current queue of evaluations, and are performed when other evaluations  
are complete. No time limit is applied.
<<<

Hope this makes it clear.

Cheers
Patrick
