Can you please check the Oracle client you are using? We have some problems with client which is below 10gR2 (9i/10gR1), which has been fixed in 7.0 patch, but currently we are in some process to get it out, hopefully it will be available later this week.
So before you could use the patch, the only workaround is to update to a newer version of oracle client above 10.1.
I am using Oracle Database 11g Enterprise Edition 11.2.0.3.0. The strange thing is that it works fine on my colleague’s machine. I even copied the preferences file from his sql navigator to mine, to check if it has anything to do with Navigator preferences.
Did it work after you coping the preference file from others? So far I couldn’t reproduce your problem yet even with some related options changed in preference. If you still meet this issue can you please send us your profile to a further check?
Can you please double check again you Oracle Client version but NOT oracle database version?I reproduced you issue with client 10g1, please let me know which client version are you using, thanks.
We are on the way to getting 7.0.1 patch out soon, you can either update your client to a newer version, or wait for a few more days about our new 7.0.1 version with this issue fixed.
