The TImageList component will not work under win32. In the bug report are 5 reports about this (454, 594, 654, 790, 847). It is the same problem always. I don't know where is the bug and how write a patch. Perhaps there is anybody, who knows what is happening before lazarus crashed. Please tell is here or in the mailing list. So it will be updated soon, I hope so...
Thanks.
