I have just updated several “run time” licenses to 4.06 and this has made an experiment made in 4.05 run very slow. We’ve already opened all the experiments in 4.06 and saved them to see if this would allow the programs to run more quickly, but have had no luck. Additionally, the reaction times are not accurate. They are coming up as ~35000 ms instead of 1000 or 2000 ms. What can I do to either have 4.05 and 4.06 on the same computer so I can still run the original experiment on 4.05 (that was working very well) or perhaps change anything to get the experiment to speed up and have the reaction times be accurate? Any help is appreciated.
