well, Hi. I've got a problem, not actualy a problem, but some strange and wonderfull things happening. To not to explain in long terms , here is actually, what happened. Somehow navigation bar (small horizontal bar below the instrument panel (don't сonfuse it with project navigation tree, which is actually for the same purpose, but displays information more extensive)) stop to show actual path of the file. It simply shows one path and when I open another file it still shows old file path. Strange, isn't it? I think, if I restart IDE it became to work properly, but why should I restart it?! The actions that probably may cause this wrong behavior of small navigation bar was these: splitting, unsplitting windows. That is all. Many thanks. And just to say that: thank you for making this amazing IDE. Now that is accurately all.
