I recently installed Mavericks on my 2011-era iMac and hated the new Pages (5.2) so much I've gone back to using the previous version (4.3). The problem is, when I open a Pages file (even one I haven't "upgraded"), Pages 5.2 is the one that opens. I've put Pages 4.3 in my dock and I can open it directly and navigate to a file, but I'd rather just be able to click the files on my desktop like I've always done and have them open in the version of Pages I want. How do I make the version I want the default one? Barring that, is it safe to just delete the new version? Can I re-install it from the App Store if/when I decide I want it?
