This should not happen, but I have found that the beta version of the bugged mess known as Synapse 4 is actually more stable than the released version.
It is still a bugged mess, and with no way of going back to Synapse 3, it is the best of a bad choice.
After performing a clean install of Synapse 4 released version, it has frequently crashed, and had to be restarted. This on every computing session, without fail. To see what is being selected, I have Synapse open at all times. When it disappears, I know that it has crashed.
The beta version has not once crashed. It has other annoying habits, such as not recognising when I am using a web browser, or Microsoft OneNote. However that is also present in the released version.
Quite honestly, I do not understand their rationale of restricting Synapse to only recognising certain programs. It will cost them sales.
