Re: FLASH: "Clicking" sound problem

[p-h]

Hi John !


Thank you for all those *sound* ;o))) advices - it's quite easy (or so do I

believe) to understand despite the fact that I'm quite new in this field.

I'll try the various solution proposed and let you know when it's OK.


Thanks a lot anyway for having diverted some of your time to answer my

question.


Have a nice week-end


P-H Steyt
