Additionally, I gave regedit a try. It would actually render and launch properly. However, when opening a folder it may work and then a second folder opening will not show the contents but just open some space as if the sub folders are there but not listed. A further click on regedit and it will crash, giving an error similar to the following: X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 63 (X_CopyPlane) Serial number of failed request: 1801 Current serial number in output stream: 2251 So, it still seems "X related". Again, XQuartz was installed from MacForge (X11-2.3.2.1.dmg) Must be something underlying causing these problems.... iveand
