Hello Source-Navigator Team. I've just started playing with SN 5.0 and I can not get it to recognize classes, methods etc... in my ITCL source. I've even tried a very simple itcl source (see below.) I'm running under Window NT 4.0 SP6. I also tried SN 4.5.2 and get the same results. It ignores the classes, treats the methods as functions. The only "classes" I can get it to recognize are tcl namespaces. Also, if add an inherit foo line to the Timer class I get an error when the code parses. From what I've seen, SN looks really useful. Second Question: whats the proper way to install 5.0 on windows? The binaries (.zip file) doesn't have an installer like 4.5.2 does and there aren't any instructions. Thanks Rodger Hughes.
