I'm doing a program in Mathematica 10 and I need to use different buttons like Button["Start", Module[{}, 'routine']]

It all works wonderfully when the routine takes very little time, but when I try to create buttons similar to that and the routine requires several minutes to be completed, then I click the button just after two, three seconds, the process stops.

Why? How can I fix this?

    The default evaluation method is "Preemptive". Try Method->"Queued". – Karsten7 Aug 19 '15 at 15:37

In the documentation of Button, under Options -> Method, it says:

By default, button functions are evaluated on a preemptive link and time out after 5 seconds:

DynamicModule[{a = "start"}, {Button["does time out", Pause[6]; a = "end"], Dynamic[a]}]

Use Method->"Queued" to evaluate button functions on the main link, which never times out:

DynamicModule[{a = "start"}, {Button["does not time out", Pause[6]; a = "end", Method -> "Queued"], Dynamic[a]}]
