Do you know that MQL5 has classes?

I am getting an access violation in the OnCalculate function

It appears to happen when I cover part of the window leaving the leading edge exposed. If I don't cover the window, it appears not to happen


2014.03.24 21:47:01.178 Access violation read to 0x0898A450 in 'C:\Program Files (x86)\MetaTrader ECN - FXOpen Indicators\MQL4\indicators\custInd.ex4'


This seems to suggest that there is a problem reading the indicator executable, but this happens after the indicator has already been running for some time. I do have the source open in MetaEditor. Could this be causing the problem?

Can someone suggest how I might find out what the problem is?

Thanks

Seems your are not alone.

Which build are you using ? Do you try to recompile ?

my guess is it's an import DLL causing the problem
