Trying to start my new Delphi2007 in a XP system running WindowBlinds 5.0 I was met by the error message "Access violation at address 2003F2A0 in module rtl100.bpl. Read of address 00000004" Unloading WB solved the problem. The skin used was "Growler". Using the Windows XP skin mad startup possible but file editing was impossible. Delphi7 is unaffected by WB. I have not tested other versions of WB, nor using Vista instead of XP.
