When IWS has been running for a long time, you could experience intermittent application crashes when you close IWS. The Global exceptions handling feature was updated to address this issue. All unexpected application crashes are now separated into two types:
Simple Error
Critical Error
Simple errors can now be ignored by you and while Critical errors can not be ignored, you will now receive a descriptive error message and IWS will be properly closed.
This issue was tracked as Item #140853.
