Hello.

I made an vba excel application.
(when i do an entry in a specific cell, the cell is validated by an vba function and some network communication is made).

However, when i do an entry in such a cell and the vba functions are performed, i see that i can not use the "UNDO" button anymore.
(when i do an entry in other cells that don't call the functions, the undo button doesn't has that behavior)

very strange.
how does it come and what can i do?

thanks in advance
