Just downloaded and installed 3.0.2, running on QT 4.8.6, OSX 10.9.3. Occasionally, maybe every 20-30 edits, Huggle will spike in CPU to over 100%. The application then becomes unresponsive and can take about 15 seconds or so to return to normal. Any ideas on this? Apologies if this is a duplicate report.
