We have become aware of an issue affecting users of the Firefox 4.0 web browser. Specifically this version of the browser seems to have an issue with our dropdown menus not being selectable
For example you may not be able to select an autoresponder service from a dropdown menu
We are working on a fix for this, it seems isolated to this version of Firefox as beta versions of upcoming versions of Firefox are working fine.
How to fix
For now, our recommendation is to switch to using the Google Chrome web browser when editing your OptimizePress pages. You can download Google Chrome for free here
