Confirmed that Histogram is available for other VMs on the same machine.
I disagree with your assessment, however. If a feature is not usable, a checkbox
should be disabled. There's no reason to check the box and then be told, no,
it's not really available. I don't use VVM often enough (e.g. not every day)
that I can recall why such settings are the way they are when I open the app.
For example, does unchecked mean
- not available in this VM?
- expensive operation! disabled by default!
- you unchecked this box the last time you opened VVM
Personally, I think that in the future VVM should support more configurability
that persists across sessions, so I would expect that I could uncheck the Histo
box and have it remain unchecked when I next open VVM. While that's not a
feature now, that would be in line with other GUI apps with many user-selectable
If you don't feel the tooltip is easy enough, I'd just add a single line of text
below "refresh rate" in this case, saying "Histogram not supported by this VM".
But that's just me...
