Thanks for the detailed response Oscar. In my post there was a second issue, could you reply regarding that one too?
Cubase freezes if you try to replace a file in the PDF print dialog due to a duplicate name:
Repro:
Open a track in Score Edit
Switch to page view mode
Print the score to pdf. Use a file name that already exists when the save dialog comes up
Hit Save
Cubase is now unresponsive. You cannot use the mouse or keyboard to click on Cancel or Replace, to dismiss the save dialog.
The only way out is to force quit.
