G'Day All, This is kind of Delphi related..... I am running D3.02 NT4WKS SP4. I had a need to upgrade from TChart 3 that shipped with Delphi to TChart Std 4.01. After performing the upgrade WinHelp stopped working giving me the error dialog "The memory could not be written etc." This only happens should the help file not have been used and it is being prepared for first use. Can anyone give me some idea of the DLL's that are used by WinHelp and what version / size they should be at?? No amount of re-applying the service pack or copying likely DLL's from other machines has done the trick. Rather difficult to get work done when you can't look in the help. (Gee perhaps Delphi's help is not __that__ bad after all *grin*) Any help, pointers, suggestions GREATLY appreciated........ ------------------------------------------------------------------------ --Donovan Donovan J.
