<DIV><FONT face=Arial size=2>Now that I have good logarithmic values, I've
installed a couple of independent 3rd party free VU meter components to
visually display the values. This is working well most of the time, but
I'm having trouble with both of these components. For no
apparent reason, they freeze on the screen. The components are still
running and drawing lines on the canvas, as I've traced this through the code,
but nothing appears on the screen. If I minimize and restore the form,
the components often become invisible. They are not being
repainted.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I've tried Invalidate, but this makes no
difference, apart from some minor flickering of the component while
it is working, but not when it isn't. </FONT><FONT face=Arial size=2>The
components are being updated every 50ms. This is a 2Ghz PC.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I've tried Application.ProcessMessages.
</FONT><FONT face=Arial size=2>Any other ideas?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks,</FONT></DIV>
