Description
There is an obvious bug in TDBGrid  in Delphi2009, Delphi2009 Update1 and Delphi2007, this bug will be ?isible·if you change the BiDiMode property of TDBGrid to  bdRightToLeft, and try to cover the DBGrid in runtime or design time with any other window or component, then you will notice the distortion in the DBGrid canvas.
Steps to Reproduce:
- Start a new vcl Application
- add a DBGrid and assign it to a DataSource and let it has some records.
- change BiDiMode property of the DBgrid to  bdRightToLeft.
- run the application.
- try to move the form that contains the DBgrid beneath any other window or the Taskbar and you will notice the mess in the DBgrid canvas.
Workarounds
I've made a quick solution by (re)implementing the  WMPaint procedure in TCustomDBGrid, see my Blog.
