I found a similar problem in snmpwalk:
I search for "fan" at the entPhyicalClass level - not found
fan_1.png
I search for "fan" 2 lines before it appears - not found
fan_2.png
I search for "fan" 1 line before it appears, search finds it and moves the cursor down one line
fan_3.png
Similar things happen as you move back towards the root node in the tree. Sometimes "fan" is not found; sometimes the node that is a ancestor of fan will be highlighted for you to open.
I am using Dude 3.1
I remember search working better in previous 3.0RC versions, but sometimes it would hang if the string could not be found.
