Bug Report … SystemUIServer Crashes, iStat Menu
Because there is no way for AL (that I have found) to have the SystemUIServer refresh itself from its log, I restart it when needed, i.e. when changing locations and changing menubar icons. Some of your have pointed out that this breaks apps like iStat Menu, since it hooks itself into the SystemUIServer, but in an apple-did-not-intend-you-to-do-it-this-way.
I’m trying to come up with an elegant way of dealing with this, but until then, just disable the feature in AL.
