I toyed with a new project to get a feel for how the IDE works and I couldn't save its layout as i was exiting the IDE.I cannot remember the exact error message now.
But since I have tried again and that seems to have worked.
I am using the latest version published 16.01. I just noticed it is 32bit. Is there a 64bit one?
Coming from an eclipse user, my experience so far is far from being smooth sailing, especially importing an existing project wasn't intuitive at all, it did not recreate my folder layout, instead created some deep folder tree... code completion doesn't work either (I suspect that's because of the disabled plugin, if so is clearly major issue). Placed the mouse on a header file, right clicked hoping to find an entry that suggests it would open the file for me, did not find that.. highlited a function and asked it to tell me who is using it, couldn't do that either... now I could have screwed some in a massive way somewhere or else I must be missing something..
