I am using a trial CD installation of RoboHelp 10 with Windows 7 and attempting to define two separate content categories with a WebHelp layout. Was working better earlier today. It would compile and display in Internet Explorer but the drop down for the categories was collapsing immediately so I could not select the second category even though I could see it. I rebuilt the demo project and now it's crashing on build. Previous project from today no longer displays in Recent Projects. Is this an installtion problem?
Please add some information about your installation. What is the operating system for example?
Then wait until you have done the recording that Rick has requested in your other post at http://forums.adobe.com/message/4801196. Maybe whatever is identified in that will be linked to this problem.
