yosemite download does not start
I recently upgraded to Yosemite and want to reinstall it from scratch.
So, I logged on App Store click on the "download" button, which is active and select the "continue" button for a full download, but then other than a cogwheel indicating some sort of activity... nothings appears to happen; no progress bar, no error messages... Any ideas anybody?
iMac, OS X Yosemite (10.10.3)
