Exception - Draw Objects

[mjc4118]

I received an exception attempting to place draw objects.
I exited and restarted.
I am still receiving the exception when trying to place arrows and lines on the chart.
About every 1 out of three attempts causes the exception.

mjc4118,

What kind of chart are you using? Equidistant? Non-equidistant? Multi-series? Please try without any custom indicators as well.

[mjc4118]

2 charts open
GC 02-10 333 Tick and 667 Tick

I have custom controls on the 333T chart and Bollinger bands and SMA on 667T Chart. the error occurs on both charts. Will try later after trading day after removing custom control off 333T.
