Don't know why there are so many good reviews ! It's a real pain to get Tora to work. Using Win7 32bit with Oracle instant client 10 (tried 11 too) kept getting "unable to connect to the database ORA-38654784 missing error description" Try searching for that in google.. no such ORA error! Poor documentation, missing help file. WITHOUT CHANGING any settings, I whipped out TOAD (an ancient version btw) and it worked without a hitch. Tora is a disgrace and is putting open source a step back.
TOra doesn't seem to work at all once it has crashed. Tried restarting computer twice. And how do I submit bug reports? The bug tracker appears read-only...
