Hi Mo, Thanks for your help. The segmentation fault dissapeared when native_threads was used instead of green_threads. I shall compile tclblend1.2.3 in any case. To answer some of the other questions, I downloaded a binary release of tclblend 1.1.1 from scriptics. I did not use jtclsh wrapper script.
