Re: Problem with old version of Scintilla causing program to crash..

the dll was distributed with the IDE as part of an installer EXE and the 
package has been working fine for act least 6 years with no customer 
complaints until about3 weeks ago when a new customer bought the lauguage 
and received the IDE INSTALLER.  I had not used the IDE in some time and 
that was when I found out it did not work on my desktop. Within a few days 
other forum members mentioned having the same problem. I pull out my non 
internet connected lapnot and discovered that it worked fine there.
Since my initial posting this morning, I having been striping code out and 
try to see if I can get a change when I attempt to open a file.  The crash 
occurs when the statement to open the scintilla window is executed.
