So many bugs in InDesign!!!

1) Export to PDF (any settings) works once after starting InDesign. Then fails on any attempt to re-export. Which ever preset I use - error. Nothing special about the file - nothing!

2) Also, and I know it's not about PDF, Keyboard shortcut to start a New Document does not work on startup. I have to click on file menu and open the sub menu item New – then the shortcut works :| No error – nothing! It just does not respond to shortcuts.

BTW: Posting this by clicking "Post idea" does not mean that this is an idea - it is an ongoing irritation about updates from Adobe that does not work and #%&$%#..-up my work!
