I'm running Vista x64 Home Premium and PSQL Workgroup 10.01.042. This is the second time this has happened. My tree view in the control center has disappeared. I can't see my list of databases or tables, etc. If I try to add a server (my own machine) I'm told that the server already exists. I can't seem to track down an .ini or registry entry to obviously controls the appearance of that frame in the PCC. I know I can solve it by re-installing but I'm hoping someone has a faster "click here" type of solution.
