tried this before and just did it again - no change at all
again, any search carried out on Video and AUDIO do not even start (Limewire button does not start to turn nor does the search name appear in the header) while all other searches start - without finding any documents

I passed this problem as you suggested to the Limewire support - lets see if they can help me in anyway.

Thanks a lot for your help - it is very much appreciated.
