NinajScript Editor / Mouse Wheel causes crashes

[Harry]

This is an issue that haunts me for years, and causes a couple of crashes per week within NT 6.5.

After editing an indicator, I would typically scroll down to look for the section of the code to check or modify.

When trying to scroll down (directly after editing), NT sometimes locks up (not reproducible).

This is the error log from the trace file:

Any ideas?

Hmm .. the problem is we needed to have a reproducible scenario...

Also: No NinjaTrader code involved, only windows and 3rd party editor code. There unlikely could be done something in NT to resolve the issue. Sorry... I'll send the vendor an issue report

[Harry]

Same procedure as last year....

I just remember that I had already posted it last year, should have continued the same thread....

Do you have inline syntax checking turned on? Any difference when having it turned off?

[Harry]

Yes, it is usually turned on. But I am unable to reproduce. Happens one time in 50....

You could try having it turned off in an attempt to isolate the culprit.
