I just noticed that right now, it is very easy to mess up your budget if your localisation settings have a comma as currency separator. Entering a value of 10,50â,¬ must be entered as '10.50' to be displayed correctly as '10,50' in the budget cell. Entering '10,50' will result in a value of 1.050,00.
The dangerous part is, that selecting/highlighting any value in a budget cell and pressing <enter> will ignore the comma and result in 100x the correct amount being entered as the new value. Now the next cell is selected, and the problem repeats. Hitting <enter> several times in a row can quickly mess things up.
I have run into this problem in Firefox 50.1.0 on a Windows 7 machine.
EDIT: Restarting Firefox has apparently solved the problem. Very strange.
EDIT 2: Just happened again, refreshing the page fixed it.
