Long delay getting right-click menu from mesh objects

[Profaitchikenz Haiku]

I have a friend who was getting long delays of perhaps 10 to 20 seconds after right-clicking on some mesh objects I had positioned before seeing the menu. Before I go down the route of analysing her viewer, machine, operatying system and so on, is this a known problem? I have gone through the wiki list of debug settings and not seen anything that refers to right-click delays. They do not see the problem when touching (left-clicking) anything, but in that case no menu would pop up anyway.

It has been slow for the menus to show up today. It may have to do with the maintenance LL is doing this week. I wouldn't do anything until they finish what they're doing. The maintenance will be going on all week. http://status.secondlifegrid.net/2014/11/17/post2417/

This can also sometimes be caused by having many, high poly count meshes linked together. Not entirely sure why it would affect how long it takes for the edit menu to appear, but after some previous personal experience, it certainly does.
