Hi Arjen: It is great you were able to build and run PLplot on Linux, experience the excellent speed of the tests of the standard Tcl-related examples on Linux, and confirm the specific bug I found. If your debugging of our Tcl/Tk/Itcl/Itk/Iwidgets code finally leads you to suspect some issue with our underlying C code, then gdb and valgrind are excellent Linux tools to help debug that C code. I would be happy to answer any of your questions about using those tools if/when the time comes. Good luck with this bug hunt! Alan __________________________ Alan W.
