Seems related to a progress dialog that you are showing. I've encountered a similar issue when a process dialog was displayed while the main thread was busy. The solution is to add a call to DoEvents and let the progress dialog animate.

fanfalveto · Apr 17, 2013

Thank you.Yes that´s the problem.I try to quit the progressdialog and then all runs ok.
Thanks

The funny thing is there is no progressdialog in your code!

fanfalveto · Apr 17, 2013

There aren´t progressdialog in this code,but in other activities yes.I don´t know why affected Progressdialog in other activities to Main activity when i do progressdialogshow("xxx") and after progressdialoghide,but now i quit all progressdialog and no problem.
