Hi DonAlfredo,
Thanks for doing the test using bgrabitmap and bgracontrols.
I have tried this also and this is fine, I think what is happening is that the project was created with Lazarus Trunk on Windows, and this is the problem, I am at the moment trying some things just to verify the assumption.
The project that exits on OSX and on 1.6.02 was created with Laz Trunk, all other projects that were created with non Trunk ( even though they have been edited with trunk) all are working fine.
I have done on quick test on OSX trunk ( using all components that are in problem project) and save the project and can open this on Trunk in windows, am in middle of doing similar going the other way.
It seems like a long shot, but the problem project is one that I have only in the last 3 weeks created. It does have a rather large resource.res file, sop am also testing this as well, ( these are the only differences I can think of between this project and others).
So still trying to hammer out where the problem is, working in the dark as Lazarus is displaying no debug info to help.
