Client lockups when a mob engages someone around me

[evilkorn]

The problem I am having is when I watch people engage a mob or a mob agros someone in close proximity to me my client will freeze and I end up with the windows 7 spinning circle mouse pointer and the process is not responding. The OS does not freeze just the client.

It's a long shot but if anyone has any ideas I would be grateful for the assistance.

Edit:

Problem appears to be solved. I'm not sure if this is a glitch with vertUI or what but if you resize a chatbox by dragging it from the top down to the typing area the client will lock up, same as it did when someone attacks a mob around me. Turns out my "spam" box as I call it where I send others attacks to was too small and when the UI tried to put text there it would lock up, same as if I were to resize the box too small. So I opened that up to only show one line and the problem appears to be solved. Leaving this is the search pool so if anyone has the same problem maybe they will find it.
