Any news on this error? I am getting reports now and than from users that they get this error dialog. "Error transferring internal Bitmap using BitBlt (TeCanvas.pas, line 6586)" Out application constantly adds data to a chart, and the problem is when the system shows the screen saver or when accessi...

With the latest release, TeeChart v2011.03.30407, I also get this error on line series when the pen width is 2 pixels.
If I change to 1 or 3 pixels for the lines pen, it renders ok.

It worked in the release 2010.02.20202.

I just tried it on 32-bit Vista and Windows 7 x86, and as you say, it becomes unresponsive for about 4-5 seconds, but at least returns. However, on 64-bit versions of Vista and Windows 7, the application never responds again, I have to reboot (cant even kill the application from Process Manager). Be...

I am using Build 2010.02.20202, but it was the same in the previous version.

You should press the button in the test application, and then quickly try to resize the application form.
On Windows 7 x64 (the only OS I have tested this on) it hangs the entire system.

I am thinking that this might be the resulting error message caused by another fault. So far I only have reports about this error from an IBM Thinkpad T61 laptop with a Intel graphics GM965, driver version 6.14.10.xxxx on Windows XP. I have never seen this error myself, I have only been informed by ...

I just narrowed down another error I have seen on the TChart2010 version. Sometimes we have experienced that the entire application hangs (deadlock), and this started when we moved to TChart2010 from previous version 8. I was just able to create a small example that can reproduce this error. If I fi...

I think that the best chance to reproduce this error is on Windows XP, using the TAntiAlias tool on a TChart and when the computer enters some kind of energysaving during the night when no one use the computer. So far I have only seen the error in the morning when the system has been idle for a whil...

No, it happens when no one interact with the application..
The only thing that takes place is that the application keeps filling the series.
There is also a chance that the error comes when a computer enters some kind of energy saving mode?

BTW, we are also using the TAntiAlias "Tool" on the chart.

We are also seeing this problem, but we are only using FastLine and Area series. In most cases everything works just fine, but if I leave the system during the night I often find messageboxes on the screen in the morning saying the following: Error transferring internal Bitmap using BitBlt (H:\Steem...
