Well, if you've opted in to beta updates, then the latest stable release will prompt you about newer beta releases. If you don't want that, opt out of beta update notifications.
How do you run Beta version without having to update every use?
to be clear.. this is what is happening:
step 1: open Chrome
step 2: type in 'editor', auto completes to editor.construct.net
step 3: I get this message
step 4: I click update
step 5: use C3
step 6: done with C3 for the day, close browser
I get step 3 every single time I repeat this process. So if I use C3 5 times in one day, I have to click Update 5 times in one day. It's like it's not actually updating.. it's not a new version.. it's the same beta version but it keeps asking me to update to it. Why does it think I'm still on r142?
