Strange colors in control elements on Windows Vista

[Windwalker]

Hello there,

I upgraded from TeeChart 4 to TeeChart 8.

Now I tested my charts unsing Windows Vista and I experienced some strange color behaviour.
In some of my charts (not all!), the control panels containing elements, like checkboxes etc, which are used to control the chart, are layered with a red background color.
This occurs only on Vista, on XP everything is fine.

I would greatly appreciate, if someone could give me a hint, to deduce the cause of this behaviour.
Thanks!

Hi Windwalker,

If I understand correctly those controls are not chart editor controls, are they? If so, can you still reproduce this behaviour removing all TeeChart references from your application or a simple application without TeeChart?

Thanks in advance.

You're right.

Thanks in advance.

To remove all TeeChart from the respective form would impose a lot of work, since nearly the whole code in this form works with the chart.

The application I am working on contains many Delphi VCL forms, some of them contain TeeChart instances.

The strange colors appear not on all forms that contain a chart, but on most.

So far, I have not been able to figure out the difference, which causes this behaviour.

Hi Windwalker,

As you'll understand, we need to isolate the problem to identify it. Even more, we have to be sure that the problem is a TeeChart problem, and that's why Narcís suggested you to check if the problem still occurs in non TeeChart applications.

This is also why we use to ask our customers for "simple example projects we can run as-is to reproduce the problem here". Because it is easier for us focusing on the real problem.
