WPT close all Browsers after Test completed

[demin]

Hello,

my problem is, that after a Test finish all Browser all Browsers were closed.

Here my wptdriver.ini:

Code:

[WebPagetest]
url=http://127.0.0.1/
location=Local-WPTDriver
browser=chrome
Time Limit=120

[chrome]
exe="C:\Program Files (x86)\Google\Chrome\Application\chrome.exe"
options='--load-extension="%WPTDIR%\extension" --user-data-dir="%PROFILE%" --no-proxy-server'
;installer=http://www.webpagetest.org/installers/browsers/chrome.dat

[Firefox]
exe="C:\Program Files (x86)\Mozilla Firefox\firefox.exe"
options='-profile "%PROFILE%" -no-remote'
;installer=http://www.webpagetest.org/installers/browsers/firefox.dat
template=firefox

[IE]
exe="C:\Program Files\Internet Explorer\iexplore.exe"

location.ini:

Code:

[locations]
1=Local
default=Local

[Local]
1=Local-URLBlast
2=Local-WPTDriver
label=Local

[Local-URLBlast]
browser=IE 11
latency=0
label="Local - IE 11"
connectivity=LAN
;browserExe=pagetest.exe
;key=TestKey123

[Local-WPTDriver]
browser=Chrome,Firefox
latency=0
label="Local"
connectivity=LAN

Any ideas why this happens?

Best regards
demin
