SQL Navigator looses bookmarks (4334914)

There is an issue with bookmarks in SQL Navigator 6.2 (in previous versions this works fine)

Steps to reproduce the problem:

1) Log on two different schemas/users
2) Open a new SQL window
3) Put two or more screens of text or open large sql script (2 or more screens)
4) Go in middle of script and add bookmark: CTRL+SHIFT+1
5) Now switch to another schema (session) - choose it in combo 'Current Session'

Error: Script scrolls to the top of it and loses all bookmarks .

In SQL Navigator 5.5 all works fine.

WORKAROUND:
None

STATUS:
Waiting for fix in a future release of SQL Navigator for Oracle
