Item 4 only happens on Solaris JDS (Gnome). On Solaris CDE or Ubuntu Gnome, it not happens. The trick is we have to call `{EV_GTK_EXTERNALS}.gtk_container_check_resize' after shown the EV_GRID in the Errors and Warnings Tool.

Now, in `{ES_ERROR_LIST_TOOL_PANEL}.show', we do a fake width query. The width query will call `{EV_GTK_EXTERNALS}.gtk_container_check_resize' indirectly on Unix platforms.

This bug is fixed in revision#71456.

Thanks for your report.
