A strange question

[valgaba]

In an application that has only one QTIME that updates the local time in a QLabel, the application is built on windows with qt 4.6.2 and mingw32 both com windows vista seven is perfect and Sp3 Xp is also perfect, but XP SP2, from time to time 5, 10 seconds, the cpu goes to 100% of resources for a moment about 3 seconds, blocking the full implementation by making the QTIME not be updated. I would like to know why this behavior in XP SP2 Any ideas?

Thank you very much

Sorry for my English

En una aplicación que solo tiene un qtimer que actualiza la hora local en un qlabel, la aplicación esta construida en windows con qt 4.6.2 y mingw32, tanto en windows vista com en seven va perfecto y en Xp Sp3 también va perfecto, pero en Xp SP2, cada cierto tiempo 5, 10 segundos la cpu se pone a 100% de recursos durante un instante unos 3 segundos, bloqueando la aplicación por completo haciendo que el Qtimer no se actualice. Me gustaria saber porque este comportamiento en Xp SP2 ¿Alguna idea?

Muchas gracias

This very well may be a local system issue, not necessarily a windows issue.
Does the CPU spike happen only when your application is running?

[valgaba]

Exactly, only when the application runs.

Then its not an OS issue, but an issue in your application.

It's definitely a problem of QT component must
being or QTIME or QFilesystemmodel, since my application works perfectly in all windows less than in XP Sp2. I will start to ring components to find the cause.
And tell them.
