I have this version installed on 2 different computers and starting this week-end the program started behaving badly by being very slow to load a file, doing an automatic gain control and re-saving it. It does that on both computers, why? I tried fixing it using Control Panel Programs and features and restarted my computer but the program is still slow on both computers, why now and why. It never acted like that before. I tried installing the new version 9.4 and it was the same so reverted back to 6.63.
