BUG: Chart area cannot be repainted properly.

[brain337]

It is about teechart 7.0.1.3.
You can see the bug on attached screenshot image.
When chart objects are displayed on a web page, as I shake swiftly over it with another iexplorer window several times,
chart area would be displayed a broken image mixed up with that of the iexplorer window shaken.
I wonder whether 7.0.1.3 can manage this bug with some other methods or I have to upgrade teechart's version itself.
Would you please show me the way to solve this problem ASAP?
Thanks.

Hi brain337,

Latest TeeChart Pro v7 ActiveX available at the client area is v7.0.1.4. Can you please check if this version solves the problem at your end?

If it doesn't, can you please attach a simple example project we can run "as-is" and let us know the exact steps we should follow to reproduce the problem here? Could you also let us know the exact environment you are using: operating system, browser version, PC features, etc.?

Thanks in advance.

Hello,
I issued same error a few weeks ago.
I attatched test source code and screenshots at this time.
You may see that with attatched source code or may not.
Anyway, the more embeded charts are in webpage, the more frequently this error happens.
This is concerning to version : teechart 7.0.1.3.
It is more likely to happen in Internet Explorer 8.
Please show me the way to solve this problem.
I need patch download or other methods to remove this phenomenon ASAP.
Thanks bye.

Hi brain337,

I'm not able to reproduce the problem with your code. I've ran it many times both with TeeChart v7.0.1.4 and v8.0.0.7 and I always get the correct result.
Please, try to arrange a simple example project we can run as-is to reproduce the problem here and consistently.

PS: I've merged the new topic messages with the old ones to have a correct tracking.

Hi,
I attached source which seems to reproduce error situation everytime.
You can reproduce it easily with violent shaking a duplicate I.E window of the attached source over another.

Thanks bye.

Hi brain,

I'm not sure to be reproducing the exact problem here. I can see a window trail when moving any window if I move it fast so I don't think it is a TeeChart problem but a windows. If I disable System properties/Performance Settings/Visual Effects/Show Window Contents While Dragging option it doesn't happen. Could you please try if it solves the problem for you and if it is an acceptable workaround for you?
