Thanks for the details.
After an initial test, I observed the issue as you mentioned by following your steps using the latest version/fix. I found Aspose.Cells.GridDesktop errors out when performing Copy\Paste with comment. I followed the following steps:
- Add a GridDesktop control to a form
- Insert a comment into a cell
- Copy paste the cell with the comment
Exception: "An unhandled exception of type ‘System.ArgumentOutOfRangeException’ occurred in mscorlib.dll
Additional information: Index was out of range. Must be non-negative and less than the size of the collection".
I have logged a ticket with an id “CELLSNET-46244” for your issue. We will look into it soon.
Once we have an update on it, we will let you know here.
