Re: Multiple selection causing application crash

> Before working on an newer wrapper, I'll follow your suggestion to trace 
the app crash.

I was not able to produce a stack trace inside a debugger, but I inserted 
diagnostic code in my code, particularly inside the Scintilla wrapper, and 
I found what command caused the crash.

It was a call to the command SCI_GETSELTEXT() that I did not suspect to 
occur in a piece of code executed every 500 ms to update a value in the 
app's status bar.

I could not tell why this command crashed when called with multiple 
selection. Could it be related to the buffer size? I can post code if you 
wish.

Anyway, I solved the issue using a different approach with the commands 
SCI_GETSELECTIONSTART and SCI_GETSELECTIONEND.

Thanks you for your help.
