I can appreciated the difficulty in implementing an undo history in SS since you are dealing with a wide variety of object types. While it appears a multi-level of undos can be used, the current implementation reduces this to a mere single level. I have produced a short video demonstrating the problem.

(Win 7 64-bit, SS 2.7f, SS Beta, and SS-Pro 2.91d)

Hmmmm ... that's odd. It looks like it is limited to the undo's 'delete' because if you try moving an object several times there are multiple levels of undo.

As you have noted, it happens with SiteSpinner 2.70f. It also happens with SiteSpinner 2.70c. So it may have always been that way.

We will have to look into it to see whether it is an error or a limitation. Either way we will try to improve it.

Thanks for pointing it out.
