Conflicts And Merge
Since there is a period of time between the bug update from Bugzilla and upload of your changes to Bugzilla, bugs can be modified on the Bugzilla server by other users at the same time as you modify them. These changes may not conflict with your changes - for example, you modified the bug status and some other used added a comment. In this case the changes will be automatically merged when you download the bug updates from Bugzilla or upload your changes.
However, there is a number of situations when changes made by two users are not consistent; for example, when both users change the same field. In this situation Deskzilla will detect this inconsistency during the synchronization (download or upload) and will show the notification about the conflict and synchronization problem in the status bar 
. Click the conflict icon 
to see the bugs which have conflicts. Right-click one of the bugs and select Merge (press CTRL + ALT + M).
