The hotfix addresses an issue that occurs only when a user’s Skype client crashes during a Skype IM session, which may in some cases result in the last IM entered or sent prior to the crash being delivered to a different IM contact after the Skype client is rebooted or logged in as a new user. Although we cannot determine precisely how many users may have been affected by this error, we believe the number is small given the very specific circumstances under which the error occurs.
During further investigation, we confirmed that not all Skype products were affected by this error as originally reported. We can assure that users of Skype 5.9 for Windows, Skype 2.8 for Android and Skype 4.0 for IOS have not been affected.
In addition, we have fixed File Sending on the desktop versions of Skype where it was not possible to save files for users who have a hard disk drive in FAT32 format.
