Trying to edit a morphology-based visual filter, based on AFAT, but the drop-downs that appear after I type @ comsume vast amounts of CPU and take 3 to 5 seconds to appear, and then each click on the dropdown, or each keystroke takes another 3-5 seconds to cause any response. It's taken almost a minute to create a simple filter with two verbal forms (imperative, insistent imperative, etc).
Not sure where the CPU is going but it's pretty unusable as it stands.
