Even I am also facing such problems and it is not a technical glitch to be sorted out by ISC. Clear history of the browsing data and check the 'clear cache'. it would sort out the problem and update your browser. Meantime when you have to re-login while working, get logged in and press the back button while you will get the login page again. Again you go back to the back page by pressing the back button (left arrow on the webpage pane), now you will get the already typed matter. you can append it or straight way post it by clicking 'Submit response ' label.
It regularly happens to me while working on ISC and I do the same thing. In fact, this is the same one which Ms.Saroja wanted to convey exactly in her response. While editing also, we face similar problems. However, the matter would be brought to the notice of the WM for suggesting remedial action,if any.
