The only time i have ever seen this happen is when the meory gets too fragmented on the device that's running the management console. The usual way to resolve this is to first try logging out of the windows account, but if that doesn't get it, then reboot the device. One of those two has usually always cured this for us, but in the event that niether of these solves it, we would then reboot the core server itself, and even sometimes reboot the database server, and the follow that with a reboot of the core. We've never had to actually reinstall the console on a device to fix it though.
lot of data are asved in %temp% and also .net temp data.
