I've just upgraded to 1.7.4 and found that gitk does not work:

---------------------------
Error in Wish
---------------------------
Can't find a usable init.tcl in the following directories: 
    C:/Cygwin/share/tcl8.4 C:/Cygwin/share/tcl8.4 C:/Cygwin/usr/share/tcl8.4 C:/share/tcl8.4 C:/Cygwin/library C:/library C:/../tcl8.4.1/library

This probably means that Tcl wasn't installed properly.

---------------------------
OK   
---------------------------

Process Monitor shows that C:/Cygwin/share/tcl8.4/init.tcl was read successfully.

wish84.exe also tries to access the following files outside the C:\Cygwin directory, none of which can be found.
C:\usr\share\tcl8.4\init.tcl
C:\share\tcl8.4\init.tcl
C:\Cygwin\library\init.tcl
C:\library\init.tcl
$PWD\DCtcl8.4.1\library\init.tcl
$PWD\Ctcl8.4.1\library\init.tcl

Any ideas how to resolve that? Where can I look to gather more information about what causes the error?

(I also tried reinstalling gitk, git-gui and tcltk.)

Thanks,
Alex
