I was about to post this in the other topic but noticed you asked to do so in the bug reports.
Luckilly i found about the F5 thing while reading another post (you could have told me about it!)
Ignore the "retro" look of the task bar (it's windows 7)... I had my reasons for making it look like this... Those reasons don't have much logic behind them, but i'm too lazy to change it now
this is full screen, i can see the bottom now, but everything else looks blurry for some reason (i wouldn't want to use it anyway, even if it looked fine as i like to be able to see my unrelated notifications)
This is the Portuguese keyboard. (taken from wikipedia)
I don't know how to format it to fit for the forum, but thankfully both the ? and the = can be seen.
At first i tought it was related to the Shift key, as i need to hold it and press the respective key, but i remembered (and went to re-check it) that \ and | (wich requires Shift), share the same key, and both work, so i have no idea what the problem may be.
Don't bother with it too much tho, they are just minor nuisances (i guess that other people could be annoyed by them tho, but doesn't seem very likely)
