--- Comment #3 from Anastasius Focht <focht at gmx.net> ---
Hello folks,

confirming.

I lost my analysis here due to Firefox crash (writing half an hour into the
comment field) hence you only get the short version now.

The launcher uses 'CreateDialogIndirectParamW' to create a dialog and crashes
shortly after.
It expects a redraw/paint handler to be called inside dialog creation.
Wine doesn't do this, only calling 'ShowWindow' (which doesn't trigger
repaint).

Any WM_USER after the dialog creation triggers a crash because some instance
data is missing which ought to be allocated in paint handler.

I added an 'UpdateWindow' call directly after 'ShowWindow' in
'DIALOG_CreateIndirect' to trigger the paint message and it made the launcher
work.
