Are you using the latest version of PicoScope? 5.13.07

Yes

OK, I've tried that method but I still get the same result: Excel locks up and I have to force quit it.

Does it matter that I'm running on XP?

I am using an ADC-10 and I'm trying to get the data to transmit into Excel using DDE.

I run PicoScope and it reads the input as I would predict, however when I enter "=PLW|Current!Value" in excel, excel freezes up and I have to force quit it. PicoScope continues to run fine though.

Please help...
