I have 5 DLT's on a system and since I last made changes I am having problems. On one DLT the text has printed skewy/broken next to one button, while the other buttons are fine. On the others for some but not all buttons the label reads with the default "Button x", in all cases the buttons function as programmed. Points of note, My DLT's are firmware v2.1.00 and I am using Toolkit v1.12.1. I first had this issue when I moved from a native PC to an Apple running windows under VMware and potentially more relevant upgraded to the new version of Tool kit. If any one can shed any light on the issue I'd be most grateful.
