IE disconnected bug

I have a problem when running game in IE only. I log in, do various stuff, navigate, train, etc., then I start doing practice. At any point, IE can disconnect me from the site (log off) and not telling me. As of result, I can still do practice laps, get reports, but it won't let me save. When I try to exit page, game prompts me to save. I accept, then it ask me if that's ok to navigate away from the page. I accept, then it redirects me to the login page. I login, go to practice again, laps are gone, but nothing was save. As of result, I lose data. It only happened on IE. Tried also with Chrome and Firefox, no issues.

Alin - I use IE and have never had this issue.   You may want to consider resetting IE to factory defaults.  Good Luck!

It is at factory defaults.

I only have ie 9 & have not experienced this.

If it helps Alin, I am running version 9.0.8112.16421

It doesn't help. I run IE 8. I just wanted to tell this to game developers, maybe it's something they can relate.
