Frank Lettau Dear Kai Heng Feng,
thank you so much for your kind and detailed response. I ran those patches, but unf. nothing has changed ... Since all the components should be pretty much standard, there should be others reporting same or similar bug.. all the best and thanks again - Frank Lettau - ... this is what somebody else (<[email protected]>) wrote: Thanks for the bug report.
