Blocs 4.3.2. Постоянные проблемы

The Preview for all browsers stopped working after the update. Incorrect work with the display of text blocks, constant crashes and glitches Blocs 4.3.2. For six years of working with the program, basic errors have not been eliminated. The program lives its own life, without a predictable result. Will it always be like this or is there a specialist who can fix it and pay him money?
