Re: Error transferring internal Bitmap using BitBlt

I think QC 88382 is fixed since it is in the list of fixed bugs in Delphi and C++ Builder XE Update 1: http://edn.embarcadero.com/de/article/40984/ If Embarcadero compiles TeeChart DCUs for their releases, then this issue should also affect TeeChart.

Re: Error transferring internal Bitmap using BitBlt

This QC report may affect this bug. Is is fixed in Delphi XE Update 1.

The error only appears a few times a week and is not related to user input (zoom/pan) or adding data to the chart. We use t...
