No, it might be a bug in IBExpert causing the problem.

I have just done exactly the same thing as you did, except that I did
it using ISQL. It worked perfectly, with no rebooting, restarting or
anything like that.

Check your firebird.conf setting for UDFAccess: it should be the default --

#UdfAccess = Restrict UDF

For a reality check, do a DROP EXTERNAL FUNCTION, then redeclare it,
making double-triple-sure that you have not accidentally included the
".dll" extension in the MODULE_NAME argument, as it [wrongly] appears
in the declarations in ext_funcs.sql. As it appears there, it is not
recognisable syntax for any external function declaration. On
Windows, the module_name 'FreeUDFLib.dll' would resolve to
'FreeUDFLib.dll.dll' which, of course, cannot be found.
