Reader DC Tools to Select or Highlight text not working (or only sporadically)
i using adobe acrobat reader dc v "2015 release | version 2015.020.20042" on windows 7 pc. it has worked great forever has developed, in last couple months, annoying habit tools seem 'check out' , not work. may start working again later (after reboot, or passage of time, or due other software change?). cannot forced work again exiting program , restarting it. i can find pattern why starts nor why stops. it affects many documents (and documents same, once issue begins). not matter of me trying highlight image (rather text) - can highlighting text in long document , cannot (except 1 word)... same paragraph. it not think i'm using acrobat/pro - know reader , limitations. feature works , not others. affected tools i've seen not anymore: hand (pan), select text (can select 1 word -by double-clicking), highlight . i have tried "update" software , reported being date. i have uninstalled app , re-installed adobe's website - , problem still re-app...
