Get_Property (OpenInsight 32-bit)

I use Get_Property ARRAY property to get a data from an Edit Table. It's a large Edit Table and returning the data takes some time.
I then a few lines of code later call Get_Property again to get the VALUE of a radio button on a different window. The data returned is the same as the first call, a large string of @FM, @VM delimited date. If I call the Get_Property again with the exact same parameters I get a return value of 1, which is correct.
Anyone ever seen anything like this?

Some more information
Data has a LEN of 1,909,206 and the Set_Property ARRAY is very quick the Get_Property ARRAY is very slow.

Hi Jim,
Can't say I've seen the problem with the wrong return value before - no idea off the top of my head why it would do that, and then return the correct value on the next access.
I would expect the Get to be slower - I rewrote the Set several years ago to make it faster, so that's the difference there.

Yes, very strange.
I fixed it by storing the data elsewhere, removing need for a Get_Property.

Yes, I've seen that behaviour where get_property() could return the result of the previous get_property() call rather than the property it is being asked for. In our case it wasn't related to the amount of data through. It seemed to occur when the SIZE event gets calls repeatedly through vigorous resizing AND there is a background process going on, monitored with a TIMER event. This is going back to OI v9.2.1
We never got to the bottom of it, but applied a work-around by inserted this line in any code sensitive to this
Loop while get_property( MDIframe, 'DEFPROP' ) == 'WINDOW' RepeatThis won't continue through the code until get_property() comes back with the known correct answer.
My notes on this refer back to Rev Bug Tracker #252:
There is a behavioral difference with the SIZE event when the window is called with Start_Window versus Dialog_Box. Start_Window allows the SIZE event to trigger as the window is being resized. Dialog_Box only allows the SIZE event to trigger after the window has been resized. My assumption is that the way OpenInsight handles modal processing is suppressing the synchronous execution of events.
