[ubuntu] Can LXDE show 'busy' cursor while opening apps?

view story

http://ubuntuforums.org – I can't figure out a way to make LXDE show a busy cursor while opening an app. It shows one while loading web pages though. I'd like for it to also show a busy icon while opening apps though. Without this sometimes I don't know if I properly clicked on it and end up opening two instances of the app. (Hardware)
