I just installed radar contact 4. On the main scrren under utilites i clicked on the button rebuild scenery data base, what does this mean? It better not have messed up all my other add-on scenery!Also what does debug mean? not much on these topics in the manualcheers

Rebuilding you usually do after you've added addon scenery, changed afcads etc to let rc4 know the new situation.Debug is as far as i know only when rc4 staff asks you to do so in case of some bugs, it will generate a report which they might be able to use for troubleshooting.CheersMartin
