active TCL script in two HyperMesh windows

Hi,

I am looking for a solution to make TCL scripts active in two HyperMesh windows simultaneously.

Let say I am having two HM windows opening simultaneously, I run a TCL script from a window. This file contains a GUI interface.

I expect that when I perform an action on the TCL GUI ( eg: click a button), the command will be executed in both windows

Any idea will be very appreciated. Thank you!
