Post Editor Crashes Frequently: Ongoing Bugs and Frustration

The post editor keeps also crashing and re-connecting all the time. I can write the post for 10-15 sec. Then it loses connection, I lose most of what I have written and I have to redo it. Single paragraph takes 10-15 minutes to write. I have also reported this bug about 3 months ago but nothing get resolved. This is really unusable software which I am trapped into.
