I have been doing a lot of runs, and I have noticed lag when working with the restraints or structure windows when there were a lot of objects. I have been pruning these as the project develops. However I don't see how this could be translated to a spectrum, unless theres some other data generated? I have also been pruning peaklists. Reloading the spectrum as a new experiment has a little lag when selecting peaks, but after transferring the peaklist the problem resumes fully.I loaded a new NOESY spectrum, which was the same experiment with less scans. The issue persists. A tocsy experiment from the same window, and a 13C NOESY with more peaks, do not induce the lag.Any advice would be appreciated.
