Hi.

Before i continue: DisplayAlerts is set to off (disabled).

We are running a code from python through com-automation on very huge
excel workbooks.
Now we want to comment all non-empty cells with custom comments.

After a number of cells, excel throws this message box saying "Not
enogh memory. Continue without undo?". If pressing OK ... the
messagebox comes back forever (can only shoot the excel instance
through taskmanager).

How can we programatically disable undo? Or where is the problem?

We are using o2k-sr1 (eng and german).

On smaller workbooks it works ok ... and actually the generated excel
(to the point of the mssagebox) is also OK (as it should be with all
the comments).

Please help and thanks in advance
