I am playing freecol 0.10.6, rev 10383, on a WIN XP PC.
For a good while, the F2 key brought up the Labor advisor, or I could access it from the reports tab.
At a certain point in the game, it failed to appear. And still now, it's not working.
I have quickly scanned the bug reports and do not see a report on this bug.
If this is a new bug, I could try to recreate it and provide a 'before' game. Just give me a request and I'll try to provide the file.
A saved game is almost always useful to reproduce a bug. However in this case the first thing to try is whether upgrading to 0.10.7 fixes the problem.
0.10.7 and Ubuntu fixes this problem.
It can be a 0.10.6 bug, or a Win XP related bug
For me, this 'bug' is low priority (I usually play Freecol on Ubuntu). It would become higher again if someone else finds it to be XP related.
Our windows bugs are always due to some graphics weirdness in windows Java. This sounds exactly like a crash in the routine that generates the labor report, and thus a 0.10.6 issue. So I will close this one now as `fixed 0.10.7', but you can always attach a log file and reopen if you ever see the problem again.
