Crash in WinForm Demo Application

Postby lokesh » Fri Mar 15, 2019 5:01 pm

In the ExampleDataPointTracking, when I double click on the yellow point and drag my mouse while doing the double clicking, the demo application is crashing with the following message:

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

My version is 7.2.1.4001. It is impossible for me to change from version 7 to 8. Would you be able to provide a solution please?

With regards,

I believe this is already fixed in v8.4.1.4001.
