i can not paste text. Your site not support russian.
In the screenshot you can see that text.
When i type this text and press the dot Construct down in crash.
But in english all works perfectly.
crash example in
grovel.ru/images/Documents.zip
1. open file
2. go to Event sheet 1
3. Edit Set Text to "......"
4. type to the end of line &sprite.
(You must have "????? ?? ???????"&sprite.)
~~~~~~~~~~~ -> its not "?" its russian text
And Construct 2 crash.
