Emulator confusion

openSUSE 12.3 64bit KDE Version 4.10.00 “release 1”

Could someone explain this? When I start a console (as user) and enter the following two lines…

> cd ~/.wine/dr*/'Program Files (x86)'/Vcc
> wine Vcc.exe

…my emulator starts and functions normally. But when I click on my desktop Application Launcher Menu > Applications > Vcc
whose Command field contains the following line…

cd ~/.wine/dr*/'Program Files (x86)'/Vcc;wine Vcc.exe

…I get parallel diagonal bands on my screen, and the computer is locked up requiring power off and restarting. By the way, it works under 12.2.
