Hi,

On my win98SE computer lazarus and several examples (i.e. notebooktest) crashed. It didn't crash on a windows 2000 computer.

What platform are other win32 developers working, anybody else working on win98?

I looked to for the reason of the crash. The procedure CallDefaultWndHandler in the win32 api didn't check for a nill previous window proc.

Attached is a patch.

Vincent.

Now my silly question, why is the default only handled for WM_PAINT ? Marc

I think Mattias and Micha thought it was only needed for paint. See the thread DefaultHandeler 'Patch: window subclassing, paint messages' around 4 July on the list.

Thanx Aplied.
