This is quite possible. I only did 1 patch, your initial one.
I tried to download the file now, but I get an error from the webserver.

Can you check out the latest cvs sources, and send me a diff of whatever
I may have missed ?

This would be a wrong solution, and is only part of the problem.
In each case, I have addressed the problem in Interbase. The IsCursorOpen
problem didn't exist for MySQL.

In future, please send patches for db.pp and FCL related things directly
to me. I don't have time to check all Lazarus messages (I do my best,
though) so it is better to send patches straight to me.

Don't misunderstand my message wrong, I don't want to accuse you of
anything. I simply should have checked your patches more thoroughly
before applying them. But on initial inspection, they looked OK...
Anyway, feel free to look at the changes I made and send diffs for things
you think are still wrong.
