Selenium IE driver not reliable?

Hi all,

If I am not mistaken we use selenium IE webdriver for testing using
watir-webdriver, recently I was finding many bugs in the framework I
developed using watir webdriver for testing and arrived at:

It says watir IE driver is not reliable… is there similar case with
watir-webdriver IE driver?

If yes where can I find the issues related to watir-webdriver-IE-driver?
