Hi Matt - No I'm not recreating, the data in the charts just changes
as the data in the grid is changed.

Thanks Anyway!

Anyone have any other ideas?

The crash produces no error message, just seizes up. Event viewer
just says Excel has crashed and offers:

Hanging application EXCEL.EXE, version 11.0.6560.0, hang module
hungapp, version 0.0.0.0, hang address 0x00000000.

....and

Fault bucket 205435155.

Cheers

Andrew
