It's really weird. When I click Shift-F2, the manager pane appears, but when I click F2, nothing happens.
I can't see the messages.
When an error appears after building, I can only see a red box at the start of the line in which the mistake is.
I used to see the messages but now I can't even after trying to click F2 repeatedly. And it's been so for almost a year.
How could I solve this problem?
You already tried reinstalling your IDE?
I have tried this a couple of times. Doesn't work.
When you uninstall, do you ensure your preferences are deleted too?
I've never thought about preferences when deleting CodeBlocks, so I don't know if they were deleted as well as other things.
