Has anybody else seen data loss with 1.7? Switch back and forth between documents, at some point the switching and the main menu stop working (but you can still work in the document that happens to be in foreground), and after a reset, some document now in the background will have lost its recent scribbles. It is getting me so annoyed I plan to downgrade to 1.6. See also
