Spark 2.5.4

I have had about 6 people at my work have this problem

“If I run Spark It disconnects me from internet explorer and email.”

We run IE7 and outlook 2000

Any one else having this problem?

no problem here with IE7, Outlook 2003 and Spark 2.5.4 Beta 1 (should the the same as 2.5.4 final)
