NullPointerException at method Timer$TickTack.run()

Hello, I got this error message from the market, I can't understand where is the problem, but the user couldn't download the app in an HTC Desire HD:

B4X:

java.lang.NullPointerException

any ideas? :sign0085:

That error seems to have nothing to do with downloading the app but appears to have occurred when actually running the application on a device. As a long shot, do you have a Timer declared in Globals that you are trying to start in Globals or Activity_Create?

Yes, there is a Timer declared in Sub Globals:

Dim chrono1 as Timer

and then in Activity_Create it's initialized:

chrono1.Initialize("chrono1",100)
chrono1.Enabled = True

the app works fine on several devices that I tested, I don't know if there is an issue with HTC Desire HD or WTF...

Timers should be declared as process_global objects. It may be related.
