sorry, i have been held up by lots of things - after several previous examinations i will go to hospital the day after tomorrow for 3 to 5 days. we will sell our house in the coming time and move within three months, so everything will be rather hectic, but i do not give up. sorry i did not keep the thread alive, but you will understand i had too much to do and too little time to do it.
i'll be back!
