In previous CCP4 releases CCP4/ccp4i/bin/loggraph used "bltwish" exec $CCP4I_TCLTK/bltwish "$0" -- ${1+"$@"}
In 6.2.0 this has mutated to exec $CCP4I_TCLTK/wish "$0" -- ${1+"$@"} which doesn't work on our systems, see error below I've fixed it by changing back to the previous exec bltwish, but does this new version work for other people? Should it work for me, and with what version of TCL? (I look forward to replacing loggraph!)
