This post revealed the cause of a scenario where an application was attempting to launch a html file in Internet Explorer (IE) but failing. IE launched its normal home page instead. On Windows 7 IE launched inside the bubble with the html file correctly displayed.
We determined that on citrix the browser was indeed launching outside the bubble and therefore unable to see the required html file.
Changing the user classes registry key in the bubble did not work. Setting the user classes registry key for that users session did work though. This avoids changing the key for the entire machine which may impact the way the citrix server is designed to work.
Use caution. This change impacts the way that citrix is designed to launch IE, it could have wider unforeseen consequences.
