Hello,
You are not alone. I am having the same exact problem using IE7. Although, I have been using IE7 for quite some time this problem didn’t arise until I installed version 2.3.1.
I just upgraded to 2.3.2 and unfortunately the problem still exists. It is extremely frustrating!!! And I don’t want to have to keep switching between IE and Firefox when I have to make updates to my widgets, that’s just crazy.
Hopefully they will be able to come up with a way to fix this problem ASAP!
