Thanks, I cannot see any flicker anymore! Yeah, the SVN button and DOWNLOAD SNAPSHOT button ... I should have known ...
// svn://svn.code.sf.net/p/lazarus-ccr/svn/components/callite/
This link didn't work for me, so I thought I use the 0.3.4 stable version ... This PC has no SVN software installed...
Is it possible that FBUFFER isn't freed ?
I get an Error about 11 unfreed Blocks, I'll take a look! Thanks again.
Edit: Looks like this is missing
destructor TCalDrawer.Destroy;
begin
FBuffer.Free;
inherited Destroy;
end;
