strange error in Excel

[WebStar]

hi there,
everytime I let excel opend when I lock the station I get a strange error when I try to run the macro after unlocking. If I close excel and open it again, everything works fine.
The error I recive is this:

Run-time error
'-2147352571(80020005)'
Type mismatch

does anyone knows what this error is?

thank you!

Can you post your code ?

Sounds like your declaring a variable as a certain type

The code is very big and if I don't lock the station, or I restart Excel after unlock, it works perfect. I recive this error only if I let Excel opend while the station is locked.
