Does anyone notice a long delay after pressing the compile button in XTherion, before the Therion cmd window starts echoing processing progress? Any suggestions as to cause and possible solutions? Interested in setups that do and do not exhibit this behaviour. Around October last year I swapped out my aging Win10 device for a fast new Win11 device. Soon after I noticed that XTherion would 'hang' for 5 - 7 seconds before opening the cmd window that echos Therion's progress through the thconf process. It was around the time that changes were being made to the behaviour of the cmd window, circa 6.3.3+ and I loosely attributed the lag in processing to that. Especially since otherwise Therion would process the thconfigs 2x to 10x faster than with my old device. I've recently being editing projects and needing to compile then every 15 - 30 seconds. The 6 s lag has become tiresome, especially for small runs that otherwise take less than 1 s! Thinking might be a change in Therion I just installed versions back as far as 6.0.5 from around February 2022. The problem persisted so I conclude the lag is due to Win11 or something to do with my current device, and not due to Therion. I've had a browse through Windows Security Smart Application Control and Reputation-based Protection, and disabling likely settings has had no impact. I've tried disabling Virus and Threat Protection settings real-time protection and tamper protection and also no change. Bruce
