Hi there,
I used the Therion 0.5.1 installer on a Windows XP box. Since then my Cygwin installation is messed up and I can't run Tcl/Tk applications any longer. In the registry are entries like [HKEY_CLASSES_ROOT\Applications\wish84.exe\shell\open\command] @="\"C:\\Programme\\Therion\\bin\\wish84.exe\" I think this registers Tcl source scripts to the wish84.exe from Therion instead the interpreter shipped with Cygwin. This probably causes an ugly usage mix of Windows (Therion) and Unix (Cygwin) libs. After uninstalling Therion and cleaning up the registry manually (the uninstaller should do this IMHO) my Cygwin Tcl environment is fine. Roger
