PocketCloud (logo) Window

In my android 2.2.1 (screen size is 240x320), after connecting to windows desktop, a (android) window/form containing Wyse PocketCloud application logo (big logo) is displayed in front of the desktop and I can't get rid of (or close) that window. The window/form is incomplete, I can not see the bottom part of that window/form, I don't know if there is a confirmation or any kind of button to close it. The only way to close that (android) window/form is killing the Wyse PocketCloud.

How can I solve this problem (close that window/form) ?
Is it because my screen size (240x320) is to small for Wyse PocketCloud ?

TIA,
Regards,
