LiveCycle keeps telling me that form objects are using features not available in the target version, and I should review details in the Report palette. Every bit of online help I can find tells me that I can open the Report palette using the Report palette menu button, but I can't find a Report palette menu button anywhere on my interface. It's probably right under my nose, but it's eluding me very effectively.
You can make the Report palette visible from the Windows menu. This palette contains a Warnings tab, which will show the list the objects that have functionality that is not supported by your Target Version (File > Form Properties > Defaults tab).
Each error will give the minimum Target Version that supports the features. Each dumb down the object or increase the Target version.
The Report palette menu is highlighted in green above, but you need to make the palette visible first.
