In addition to what Sean and Helen already mentioned.

Which edition of Firebird are you using(Classic, Superserver or
Superclassic)?

Also when your application shows that it is frozen, what is Firebird
doing(look in the Task Manager to see the processes)? Is Firebird
using no CPU or is it actually running? Also, if you are using
MadExcept(I'm taking a guess because of the report you are showing),
you can disable(or increase the timeout) the check for a frozen main
thread.

I'm currently using Firebird 2.5 64-bit with Delphi 7, Delphi 2010 and
.Net applications with no problems.
