You should also do all of the ordinary routine maintenance; which often makes a big difference: http://www.macattorney.com/ts.html Uninstall the copy of Flash that you have installed with this uninstaller (Adobe recommends doing this first): <http://fpdownload.macromedia.com/get/flashplayer/current/uninstall_flash_player_osx.dmg> or http://is.gd/lrnKUG Then download the latest version of Flash directly from Adobe, and install it: http://get.adobe.com/flashplayer/ Go to System Preferences (accessible in the Apple menu, or in your Dock). Choose Accounts. Choose the Login Items tab. Try disabling anything there. (You may have stay-resident software that is incompatible with Mavericks and which needs to be updated.) ___________________________________________ Randy B.
