I am using SlikEdit Core 3.4.0 with Eclipse 3.4.1. I am writing C++ code on Windows under Cygwin and debugging with GDB 6.3.5. When I step into a function, SlikEdit doesn't automatically jump to the "current" line -- rather it just opens at the top of the file. Double clocking on the callstack sometimes takes me to the current line (and sometimes not). I am evaluating SlikEdit Core for our team, and this bug makes the tool pretty much a non-starter. The default Eclipse editor doesn't have this problem.
BTW: like others I was surprised at the lack of "mouse over" support for variable values, and right clicking to add to watch. These features are a "must" IMHO.
