When running a select statement, if you right-click a field in the resultset and press 'Copy', the incorrect cell is highlighted to what was originally selected.
This issue will occur, only when having dual monitors and having the second monitor on the Left of the primary monitor.
If you move SQL Navigator to the 2nd window and repeat the steps, the issue can be replicated.
WORKAROUND:
None.
STATUS:
Waiting for fix in a future release of SQL Navigator
This should be addressed in the v6.7 beta release:
