I have recently purchased IntelliJ 12.1.4 for a new development machine. I've been using IntelliJ for over 10 years now, at least, so I am an experienced user.
The issue I am having is with debugging Java code. If am using remote debugging to a local Tomcat server. In 10.5, the last version I used and every version previous that I can remember, when I hit a breakpoint in the IDE, a blue line would highlight which line the debugger had stopped at and then that highlight would move to the current line as I stepped through the debugger (F8). With 12.1.4, the debugger breaks but doesn't highlight the current line. F8 still works, I can see changes in the debugger window, but there is no blue line showing the currrent line, only the current line number in the debugger window.
Is this a known issue or some new setting in IntelliJ? It makes source-line debugging impossible.
