I can not reproduce here.

1) What release are you running on?
2) Please
- terminate NT
- remove <install>\bin\Custom\NinjaTrader.Custom.dll
- start NT
- pull up any custom or system indicator file
- right click -> compile
- try again typign in "NinjaTrader."

[guy]

That fixed it - thanks.

After I posted that I discovered that it was happening will all packages and not just the NinjaTrader package so must have been something to do with the first time that I ran that version of Ninja.

I'm running the most recent version that could be downloaded as of yesterday (3/17).

[NinjaTrader_Dierk]

Thanks. So it was 5.1.1000.1.

What version had you installed before?

[guy]

Yes 5.1.1000.1

Previously installed was one of the betas that included Ninja Script - I can't remember which one.

[NinjaTrader_Dierk]

Thanks for feedback.

For both NT 6.5.1000.14 and NT 7.0.0.5

When you open an indicator with the NT editor and then quickly turn the mouse wheel to scroll down the code of an indicator, this may cause an exception. (This happens before any modification of the code, just looking at the indicator). I have observed this problem regularly for all versions of NT 6.5. and also NT 7. Restart of NT solves the issue, next time I turn the mouse wheel slowly.....

Please find below excerpt from the trace file of today relating to the exception:

Did not post it for NT 7, because it is a minor bug, but maybe you could check with ActiproSoftware the reasons for this.

[NinjaTrader_Dierk]

Sorry, I could not reproduce on latest NT7B5. I started scrolling mouse wheel right after double clicking on the indicator file in the indicator dialog. Works no problem here.

Thankyou for answering, Dierk. This does not happen every time, but it only causes exceptions from time to time.

I just tried 5 times and could not reprocude it either. But I know it will happen again.
