hello, 
I have bouth a new computor and updated nvda to 2020.2. currently nvda doesn't read some information. for example. when ı read something line by line it doesn't read fiew letters of first word. when ı navigate between files it is similar. it is a global problem. I am using elequence  trial mode but it happens with espeak too although not ophen. 
do anyone have any idea about reason for this problem and solution?
Best regards
