Obviously you can use MUIM_Application_PushMethod from subtask (that is what it is intended for). Calling any other method directly, including SetAttrs()/GetAttr() is illegal of course. @Andres: However I would suggest doing CPU intensive work in subtask and run MUI GUI in main task only (program design permitting).
