Flicker and Stack Overflow issues with Delphi 2007 and TC7

I am trying to move to Delphi 2007 and I installed 7.12 version (No Source) and added the quickreport package as well. In design mode I am getting a constant flicker and on any report with a chart in runtime I get a stack overflow. I read some older articles about recompiling the source or using a different qrtee file, but I would figure these issues would be resolved by now with 7.12. Can someone help me figure out what I need to do to get this to work?

Hi Brad,
Yes, this problem should have been solved in v7.12 and we haven't heard of any other customer reporting this issue with that version so far. Anyway, I'm going to send latest v7 version of qrtee.pas so that you can recompile TQRChart packages as told
here.

I did what the post you link said and replaced the qrtee.pas with what you emailed (but It was the same as what I had). The report still flickers and I still get the overflow issue.
I'm running Delphi 2007 SP2 on Windows XP SP2. QuickReports is 4.07 Pro. TeeChar 7.11. I use the old style delphi layout not the embedded designer if that makes a difference.
Should the chart be flickering in Design Mode?
Let me know if you need to know anything else about my

A bit of an update... I commented out the invalidate part of QrTee and now I'm not getting a stack overflow
Code: Select all
procedure TQRDBChart.Invalidate;
begin
// if AutoRepaint and Assigned(Parent) then
// Parent.Invalidate;
end;

Hi Brad,
We haven't been able to reproduce the problem here. It's most likely the problem is your project is still referencing/using old design-time package. You should make a clean recompile making sure TQRChart design-time packages are all removed prior to recompiling/reinstalling.

Hi Brad,
No, it shouldn't. Does it flicker at run-time?

Hi,
I have the same problem (Stack overflow but no flickering) and Brads solution works for me too.
The problem occurs only on my development system (same configuration as Brad) and not on my old Windows 2000 Workstation.
Best regards
