My Mach4 desktop running on a Win7 Pro communicating to an ESS will change the text size being displayed in the small History window at the bottom of the Operation Screen. You look at the picture I attached, and you can barely see the text. When I open the History panel, I can read the History text as usual. I don't know how why this is happening. It seems to occur following some errors during probing routines. Has anyone ever experienced this before? It doesn't cause any functional problems, but it's disconcerting. What else may be going wrong. I just reloaded Mach4 fresh to reset it, and the font came back to normal after the reload. But it has happened again.
