Ive come to realize that when I make the columns of the Date or Author bigger and i size them how i want them to be. After a while or when i close quietrss and re-open it, it resizes the columns and makes Date and Author small again, all the way to the right and overlap between each other.
Is it possible you can make those columns stick/lock to their positions?
there seems to be a problem with your quiterss.ini.
Please change a few columhs and quit QuiteRSS.
If the columns are fine after the restart quit again and backup the ini file. Anyway it's a good idea to backup feeds.db and quiterss.ini frequently.
