htc 3300 GUI problems

Hi,
I’ve installed the avast PDA version upon my HTC 3300. After installation I tried to enter my license key. Here I hit the trouble. The application does not leave the lower panel to enable the touch screen keyboard. So I could not enter my license key. It seams that the application is not set at the correct screen size or is not designed to work on a device with ony a touch screen.

Is there anyone who knows how to solve this?

Regards,
Cees
