Lost my undo R7

Suddenly, I can’t undo. Every effort is met with “Nothing to undo”.

I’m pretty sure it’s a matter of setting, but I can’t find the setting and the help is no help. It says the setting is in Options > General, but it’s not there.

[Correction] it’s there, but it asks for Max Memory used, which is set to 1024 MB. How does that equate to undo steps and why does that mean that there’s nothing to undo.

[Edit] I set it to 2048 and I now have undos. Is it just that my model had exceded some limit?

Hi Cliff -

The max memory limit is just that, yes. It does not equate to a specific number of undo steps but depends on what needs to be undone. More than 1024 MB sounds like a lot, but is entirely possible.
