We recently had to switch back from 64bit source to 32bit source due to a payment gateway issue. We just noticed that in IE none of the admin horizontal submenus are being displayed. All we get is a white box where the menu should be. We haven't done anything with the Admin Themes, Templates, or Styles. This is working correctly in FF.
We are using ML 9.0.1.2 32 bit.
I checked our 64bit version of the source and that seems to work just fine in IE.
Has anyone else ran into this issue?
