Codesite (http://www.raize.com/DevTools/CodeSite/Default.asp)
is a nice tool for logging information visually.
I use it since many years for debugging UDFs and logging SPs.

Now with switching from Firebird 1.5 to Firebird 2.1,
my messages are no longer logged to Codesite and the UDFs
communicating with CodeSite use huge amounts of CPU time.

Unfortunately, it is now difficult for me to get it debugged because
it is my favourite debugging scenario (via Codesite) which I am used
to which does not work..

Does anybody else have made similiar experiences when switching from
1.5 to 2.1?

Or does anybody know of changes in the initialization section of UDFs
which have not been documented in the release notes?
