From: "cryst" I noticed there was a comment somewhere about a bug in the compiler pre-april.
The bug was a type-casting problem that affected the building of the IDE. It was fixed by 1.0.6.
What verion of compiler are you using?
I'm using FPC 1.0.6:
Free Pascal Compiler version 1.0.6 [2002/04/23] for i386
