I created a new project and put a grid on it.
I added two columns.
I changed the name of the column headers.
I then clicked on the dividing line between the headers (as if I was going to try and resize them, though I wasn't) and got this error :

[Interface Manager Debug] Error dispatching design-time event for  instance:  Message:  "GetSurface is an invalid reference"  Stack Trace:  Cursor in unit WebGrids at 1575,39

Happens every time I click there now.

<< I then clicked on the dividing line between the headers (as if I was going to try and resize them, though I wasn't) and got this error : >>

Got it, it's now fixed.  Just a missing design-time IFDEF...
