Since installing build 2152 ( VS2010 on Win7 x64 ) the managed memory
indicator will not stay on. I can go into the options, set it to display,
close the options, the usage will show for about 10 seconds and then
disappear. Checking the options again will show that it is not clicked.
I have closed and re-started VS several times, and this continues even after
a reboot. No new (VS) extensions have been installed since before this
started to happen.
