Zoho Sheet 3.0 Release

Zoho Sheet 3.0 Release

There seem to be numerous problems with this new release.  Why wasn't any of this tested before it was released?    The last version was stable for quite some time.  There seem to be alot of problems using it with Internet Explorer 8.   Many of us are using this product in a corporate environment and we are stuck with this browser so the solution can't be to switch to Firefox or Chrome.  Shouldn't this have been beta tested before replacing the only version?
