Pasting large spreadsheet data slow in IE

[Damian]

Pasting a table with 30 rows and 100 columns from a spreadsheet application such as Excel or Lotus Symphony Spreadsheet into IE, the time to paste can be very long and can cause the editor to hang.

Do you have a sample Excel file for it. I've noticed that the pasting operation is quite slow in IE, and this is not really our code performance, but the applications performance on the clipboard operations (I mean, Word+IE, for example).

By trying your sample file, just an IE paste without editor will take no more than 5s, we're not likely to 'fix' this. Note that even a plain text area in IE cannot suffer from the mount of source code generated by this sample.

@Fred: Actually from this example, 'contentEditable' mode show better scalability than textarea, which remind us again about 'rich text area' idea ;).
