I just noticed that the problem I have been having in my software can also be seen in the demo program in annotations/vectorial/demo.dproj.

To see the problem, use the demo to create a polyline and then click on edit. Works as expected if you compile the demo in 32 bits. However, in 64 bits you will first note that the points along the polyline are not displayed. Then try to edit the polyline and the program will crash.

I am using version 6.2.1. (I just tried 6.2.2 and have the same problem.)

I hope there is a quick fix as this is a problem for many users of one of my programs.

Thanks,

Jim

Hi

It seems to be an issue in Delphi 10. We have an update that works around it. Please email us for the download.

I am using Delphi 10 Seattle Pro. As I said, when compiled for 64 bits the points along the polyline are not visible. There are just a series of line segments.

When executing in the IDE it crashes with an exception $C0000005 access violation when I just click on the button to edit the polyline. Also if click continue and then click on the polyline object. If i click on break the IDE does not open to a useful location (just at the end of the demo.dpr unit). It does this every time.

When running outside of the IDE it does not crash when trying to edit but I also cannot edit any of the points.

I just noticed that if i run with debugging turned off then it does not crash but it still does not show the points along the polyline and I still cannot edit the polyline.

Hi Jim

I can't reproduce this in XE6 using the steps you mention. Can you give me more information?
