Wow… spaces is truly frustrating with this version. If you do something (like start up Notes) and wish to go to another space and work while Eclipse boots… forget it. The focus is continually brought back to Notes. It is truly frustrating behavior that is unlike how all other applications respond to spaces.
In the prior beta release spaces was problematic, but it seems to have regressed somewhat as it is now quite annoying. Having Notes operate in the background (as spaces are intended) is not an option.
I realize this is a beta… and that is why I am providing this feedback. This issue, however, does need to be addressed prior to release.
