Very strange bug (probably related to the language other than English):
 
1) create an event "Every tick"
 
2) create an action for this event, which should change the text object Text
 
3) In this step, I am writing as shown in the attached picture
 
4) Then, in expressions window i'm choose "System -> loadingprogress" and then the system crashes
 
 
p.s. If instead of "????????: " to write in English "Loading: " all is normal
 
 
p.p.s Construct 2 (release 100), Windows 7 x64 RUS
