frequency counter do not work when frequency < 15

[codecopier]

is a bug? or by design?

Hi codecopier ... do you have an example file to go with your question? I tried out the Frequency Counter instrument in Multisim 11.0 and as long as I have the "Slow change signal" box checked, it was able to measure frequencies below 15Hz. 

Thanks!
