In recent weeks my system tray has started acting up. It would stop displaying a whole lot of icons for software that are otherwise running. This is occurring randomly, i.e. after some rebooting or waking up the system tray either works properly or it doesn't.
I had that problem over the last couple of months with 7 x64 - seems to have stabilised now though FWIW. I did install a bunch of non-critical windows updates lately. Maybe one of them helped, but I really dont know.
having this problem again more often (it never went completely).
Does not seem to be related to Explorer - Windows Explorer has not crashed - not that I noticed anyways, and it's running normally as I write, with one icon blank in the tray, and about six others not showing at all.
I've noticed that if I leave Windows alone on startup, that all apps seem to show correctly.
I think what happens is that if I start using the machine before *everything* is loaded, then the tray display screws up.
Noticed that last week, I now leave the machine good time to start and have not had problems since, hopefully it will stay this way...
I dont use sleep or hibernate so cant comment on those situations.
