I encountered one annoyance in the software that should be fixed asap. I found this out when I went to save my new project in Sketchbook Pro 6, but in the Save As bar didnt clear itself as other software does, instead keeping the name of the previous file used. This can be a problem when some one is not paying attention or forgets, and accidentally overwrites a previous file with the new. Sucky issue but it needs to be fixed.
Ive been more careful to take the time and remember to clear the Save As bar name first, each time.
