Good morning,
By selecting more than one row at the same time, the open tab crashes and the textbox of the unhandled exception appears.
Thank you.

P.S. The version is the 1.1.4.24

Dear @AlessioValbusa ,

thank you for the report! What do you mean by saying "selecting more than one row"?

In your screenshot I see an open program with the exception. So I guess you mean selecting more than one row (line) in a program. I cannot reproduce your issue, because selecting more than one line in the text editor is working fine for me and is a dayly used functionallity.

Anyway, an unhandled exception should not occur when working with the K-IDE. Do you have any additional information about what exactly you are doing?

Thank you in advance!
