The same project opens fine on windows using fpc 1.3 1.44 and latest trunk, it also opens ok using fpc 1.4.4 on osx.
My guess is that it's a combination of properties in that project for a bgrabitmap component and Laz 1.6.1 and fpc 3.0.1.
(I take it you're using the same version of bgrabitmap on all computers, including the one with trunk)
Maybe you can strip down the project on a computer which works and opening it om the problem computer, to find out which component causes it.
Also you didn't mention the
exact error message.
Is it like this: 'Scanline: out of bounds' or does it not have the ":" like you showed?
from bgradefaultbitmap.pas:
raise ERangeError.Create('Scanline: out of bounds')
