Millisecond Forums

Hi,

Our participants fill in questionnaires using an online questionnaire program, via this program they are subsequently forwarded to Inquisit web. Subject ID's are generated using a URLquery parameter. This all works fine, but for some participants we have a problem when participants have finished the task and are redirected back to the online questionnaire program. The following happens to some participants:

-The default browser is Chrome.
-However, the participant opens our questionnaire link in IE, which opens a session, after filling in the questionnaires, they are forwarded to the Inquisit task in IE.
-Here comes the problem, the redirect back from inquisit to the questionnaire program opens in Chrome.

The session was openend in IE, not in Chrome, this causes a problem since chrome does not recognize the session, so the session can not be closed.
Important to note: On some computers it is not a problem to open everything in IE when it is not the default browser, the redirect is also openend in IE as we want. 
My question:
How can we make sure that the redirecting occurs in the same browser as in which the task was openend?

I hope you can help us out! Thanks in advance
