any known bugs with acknowledge not "sticking"?
Same problem here, Anyone could make this work? Using Xymon 4.3.12 here 2013/12/6 Mark Felder <user-db141d317836@xymon.invalid>
I have this same problem on FreeBSd with the latest version. I've never been able to figure it out, but sometimes you have to just mark it blue instead of acking it.
