Hi All ,
I've had time to test Biab more with your advice and after finding and updating the Graphics drivers it seems to have cured all the problems I have previously mentioned apart from when I do a wave transfer/save.

I first thought it was when I had the 'normalise' option box selected but it appears to only happen the first time I try to save a song to waves after staring Bib, no matter which boxes are selected. The message comes up in the window that the program is not responding however it seems to complete as the little windows ring keeps turning and the resulting wave files are created OK. If I save to wave a second time it goes through perfectly alright.
Not a big problem but not quite sure why it does this.
Maybe forthcoming updates will fix it.
Regards. Jeff.
