Hello I tried the savannah bug site, but although I thought I had a log in, I seem not to, or have completely forgotten it. So I tried to register, but the capcha would not let me past, kept getting this error Please correctly answer the antispam captcha! Bad passphrase (not enough different characters or classes for this length) Warning: Savane was not able to read "" site-specific information, please contact administrators I am sure I did not get them all wrong, I even did the audio, to confirm on a few of them. Anyway onto the therion error. While drawing a rock-border, I tried to follow a couple of wall points, then decided against it, (I might have managed to end the line, but double clicking, but not sure about this) Did a couple of undos with crtl-z and got the error can't read "xth(me,cmds,22,8,x)": no such element in array can't read "xth(me,cmds,22,8,x)": no such element in array while executing "set ox $xth(me,cmds,$id,$pid,x)" (procedure "xth_me_cmds_update_line" line 12) invoked from within "xth_me_cmds_update_line $id $pid $xth(ctrl,me,line,type) $xth(ctrl,me,line,name) $xth(ctrl,me,line,opts) $xth(ctrl,me,line,reverse) $xth(ctrl,me,lin..." (procedure "xth_me_cmds_update" line 28) invoked from within "xth_me_cmds_update {}" (procedure "xth_me_unredo_undo" line 4) invoked from within "xth_me_unredo_undo" (procedure "xth_app_control_z" line 7) invoked from within "xth_app_control_z" (command bound to event) Also the menus have disappeared, (not sure if this is related) After this all I can find that I can do is move the page with right click, and change between the 3 windows using the icons or the function keys. I can open and close files in the data and configuration windows, and edit the text in all windows. Everything else I try give the same error above, whichever window I am in. I cannot even close, with the cross icon or alt-F4. Andrew
