When peak selection doesn't work there are a couple of common reasons. The
first is that you can only select peaks when Caps Lock is off. The second
is that you must be selecting peaks in the active peak list for that
spectrum. I suspect that the latter is the cause in this instance.
When you load a spectrum into Analysis a peak list is automatically
created. However, when you import peaks from Ansig export files these are
put into new, separate peak lists. Thus, what I suspect is happening is
you can select peaks picked in the default peak list (active) but not
peaks in the peak list created by FormatConverter. To solve this issue
go to "Crosspeaks:Current peak Lists" in the menu and find which peak
lists have all the imported peaks. Then go to "Experiment:Edit Spectra"
and set the active peak list appropriately for your spectra.
> also, is there a quick way to find a particular peak in a spectrum
Yes. In the "Selected Peaks" and "Edit Peak List" popup panels there's a
"Follow peaks" toggle button at the top. Set this to on and then click on
any peak row to have the selected window zoom to the peak.

This is done on a per window basis. It is set in "Window:Edit" in the
"Window peak lists" section, although you must have a window selected in
the top table to toggle symbols and annotations for the peak list.
