Recently I started using templates for my projects and I did this by editing the existing jazz production template.
In the project I created with this, I cannot set or reset a marker by clicking and holding the mouse in one of the appropriate boxes named 1-8 in the taskbar.
The box turns momentarily into green but no marker is set or reset.
When I do this on another project not created with the template it works fine.
Is there a setting somewhere that needs to be checked?
