Ninjatrader crash when indicator draws an image on a chart

[EB Worx]

Hi
I've downloaded the SampleDrawBitmap sample provided to draw an image on a chart

https://ninjatrader.com/support/forum/forum/ninjatrader-8/indicator-development/97889-adding-graphic-image-to-chart?t=99589

When i add it to my chart, the image shows nicely, but after pressing F5 a couple of times to force the indicator to reload
ninjatrader completely crashes.
Is this a bug, or is the sample not good ? I've looked for other documentation about drawing images and as far as i can see the sample provided seems good ?

Hello Erwin Beckers,

Thanks for your post.

This would be an older version of the example. Please check the revised version attached and let me know if you have any issues. (woodenBox goes in Documents/NinjaTrader 8/ folder)

I look forward to being of further assistance.
