File Open ...recently used project not appearing in Open File list at start up

When I used to open Sonar X1 the project I had previously been working on would appear at the top of the Open File list....great for starting where I left off.

Now that's not happening ..it's the same very old projects that are stuck there. The projects I'm working on don't appear there on start up and I have to look in Cakewalk Projects to open them.
I've recently done a fresh reinstall of Sonar X1 but the problem is still there. I've tried Edit Preferences but no luck.

Can anyone suggest where I might look to solve the problem ? It's not essential but it used to be a handy feature now lost.
